Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51498, here are decompositions:
- 11 + 51487 = 51498
- 17 + 51481 = 51498
- 19 + 51479 = 51498
- 37 + 51461 = 51498
- 59 + 51439 = 51498
- 61 + 51437 = 51498
- 67 + 51431 = 51498
- 71 + 51427 = 51498
Showing the first eight; more decompositions exist.
