Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177984, here are decompositions:
- 5 + 177979 = 177984
- 17 + 177967 = 177984
- 31 + 177953 = 177984
- 41 + 177943 = 177984
- 67 + 177917 = 177984
- 71 + 177913 = 177984
- 97 + 177887 = 177984
- 101 + 177883 = 177984
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 177,984 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 177984 first appears in π at position 234,698 of the decimal expansion (the 234,698ordinal-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.
