Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78510, here are decompositions:
- 13 + 78497 = 78510
- 23 + 78487 = 78510
- 31 + 78479 = 78510
- 43 + 78467 = 78510
- 71 + 78439 = 78510
- 73 + 78437 = 78510
- 83 + 78427 = 78510
- 109 + 78401 = 78510
Showing the first eight; more decompositions exist.
