Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42492, here are decompositions:

5 + 42487 = 42492
19 + 42473 = 42492
29 + 42463 = 42492
31 + 42461 = 42492
41 + 42451 = 42492
59 + 42433 = 42492
83 + 42409 = 42492
89 + 42403 = 42492

Showing the first eight; more decompositions exist.
