Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100644, here are decompositions:
- 23 + 100621 = 100644
- 31 + 100613 = 100644
- 53 + 100591 = 100644
- 97 + 100547 = 100644
- 107 + 100537 = 100644
- 127 + 100517 = 100644
- 151 + 100493 = 100644
- 197 + 100447 = 100644
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 100,644 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 100644 first appears in π at position 369,282 of the decimal expansion (the 369,282ordinal-suffix:nd 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.
