Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51516, here are decompositions:
- 5 + 51511 = 51516
- 13 + 51503 = 51516
- 29 + 51487 = 51516
- 37 + 51479 = 51516
- 43 + 51473 = 51516
- 67 + 51449 = 51516
- 79 + 51437 = 51516
- 89 + 51427 = 51516
Showing the first eight; more decompositions exist.
