Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42786, here are decompositions:

13 + 42773 = 42786
19 + 42767 = 42786
43 + 42743 = 42786
59 + 42727 = 42786
67 + 42719 = 42786
83 + 42703 = 42786
89 + 42697 = 42786
97 + 42689 = 42786

Showing the first eight; more decompositions exist.
