Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120784, here are decompositions:
- 5 + 120779 = 120784
- 17 + 120767 = 120784
- 47 + 120737 = 120784
- 71 + 120713 = 120784
- 107 + 120677 = 120784
- 113 + 120671 = 120784
- 137 + 120647 = 120784
- 197 + 120587 = 120784
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 120,784 and was likely granted around 1871.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 120784 first appears in π at position 475,506 of the decimal expansion (the 475,506ordinal-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.
