Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940644, here are decompositions:
- 37 + 940607 = 940644
- 71 + 940573 = 940644
- 97 + 940547 = 940644
- 101 + 940543 = 940644
- 113 + 940531 = 940644
- 167 + 940477 = 940644
- 223 + 940421 = 940644
- 241 + 940403 = 940644
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 940,644 and was likely granted around 1909.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 940644 first appears in π at position 75,131 of the decimal expansion (the 75,131ordinal-suffix:st 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.
