Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938904, here are decompositions:
- 23 + 938881 = 938904
- 47 + 938857 = 938904
- 61 + 938843 = 938904
- 73 + 938831 = 938904
- 97 + 938807 = 938904
- 101 + 938803 = 938904
- 157 + 938747 = 938904
- 191 + 938713 = 938904
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 938,904 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 938904 first appears in π at position 929,480 of the decimal expansion (the 929,480ordinal-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.
