Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939904, here are decompositions:
- 3 + 939901 = 939904
- 23 + 939881 = 939904
- 113 + 939791 = 939904
- 131 + 939773 = 939904
- 137 + 939767 = 939904
- 167 + 939737 = 939904
- 191 + 939713 = 939904
- 197 + 939707 = 939904
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 939,904 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 939904 first appears in π at position 851,645 of the decimal expansion (the 851,645ordinal-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.
