Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678564, here are decompositions:
- 7 + 8678557 = 8678564
- 211 + 8678353 = 8678564
- 241 + 8678323 = 8678564
- 571 + 8677993 = 8678564
- 613 + 8677951 = 8678564
- 673 + 8677891 = 8678564
- 883 + 8677681 = 8678564
- 1087 + 8677477 = 8678564
Showing the first eight; more decompositions exist.
