Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42498, here are decompositions:

7 + 42491 = 42498
11 + 42487 = 42498
31 + 42467 = 42498
37 + 42461 = 42498
41 + 42457 = 42498
47 + 42451 = 42498
61 + 42437 = 42498
89 + 42409 = 42498

Showing the first eight; more decompositions exist.
