Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490162, here are decompositions:

13 + 31490149 = 31490162
31 + 31490131 = 31490162
43 + 31490119 = 31490162
73 + 31490089 = 31490162
139 + 31490023 = 31490162
163 + 31489999 = 31490162
199 + 31489963 = 31490162
283 + 31489879 = 31490162

Showing the first eight; more decompositions exist.
