Goldbach decomposition

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.
