Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516784, here are decompositions:
- 71 + 516713 = 516784
- 83 + 516701 = 516784
- 131 + 516653 = 516784
- 167 + 516617 = 516784
- 173 + 516611 = 516784
- 197 + 516587 = 516784
- 263 + 516521 = 516784
- 347 + 516437 = 516784
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 516,784 and was likely granted around 1894.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 516784 first appears in π at position 126,286 of the decimal expansion (the 126,286ordinal-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.
