Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 564816, here are decompositions:
- 19 + 564797 = 564816
- 23 + 564793 = 564816
- 37 + 564779 = 564816
- 103 + 564713 = 564816
- 107 + 564709 = 564816
- 113 + 564703 = 564816
- 137 + 564679 = 564816
- 149 + 564667 = 564816
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 564,816 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 564816 first appears in π at position 173,933 of the decimal expansion (the 173,933ordinal-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.
