Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450162, here are decompositions:

59 + 31450103 = 31450162
101 + 31450061 = 31450162
131 + 31450031 = 31450162
173 + 31449989 = 31450162
239 + 31449923 = 31450162
461 + 31449701 = 31450162
593 + 31449569 = 31450162
683 + 31449479 = 31450162

Showing the first eight; more decompositions exist.
