Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000644, here are decompositions:
- 5 + 1000639 = 1000644
- 23 + 1000621 = 1000644
- 67 + 1000577 = 1000644
- 97 + 1000547 = 1000644
- 103 + 1000541 = 1000644
- 107 + 1000537 = 1000644
- 137 + 1000507 = 1000644
- 191 + 1000453 = 1000644
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,000,644 and was likely granted around 1911.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 1000644 first appears in π at position 76,536 of the decimal expansion (the 76,536ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
