Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42762, here are decompositions:

11 + 42751 = 42762
19 + 42743 = 42762
43 + 42719 = 42762
53 + 42709 = 42762
59 + 42703 = 42762
61 + 42701 = 42762
73 + 42689 = 42762
79 + 42683 = 42762

Showing the first eight; more decompositions exist.
