Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126090, here are decompositions:

11 + 126079 = 126090
23 + 126067 = 126090
43 + 126047 = 126090
53 + 126037 = 126090
59 + 126031 = 126090
67 + 126023 = 126090
71 + 126019 = 126090
79 + 126011 = 126090

Showing the first eight; more decompositions exist.
