Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938784, here are decompositions:
- 23 + 938761 = 938784
- 37 + 938747 = 938784
- 71 + 938713 = 938784
- 103 + 938681 = 938784
- 107 + 938677 = 938784
- 167 + 938617 = 938784
- 173 + 938611 = 938784
- 193 + 938591 = 938784
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 938,784 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 938784 first appears in π at position 798,773 of the decimal expansion (the 798,773ordinal-suffix:rd 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.
