Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78516, here are decompositions:
- 5 + 78511 = 78516
- 7 + 78509 = 78516
- 19 + 78497 = 78516
- 29 + 78487 = 78516
- 37 + 78479 = 78516
- 79 + 78437 = 78516
- 89 + 78427 = 78516
- 149 + 78367 = 78516
Showing the first eight; more decompositions exist.
