Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540182, here are decompositions:

19 + 31540163 = 31540182
59 + 31540123 = 31540182
73 + 31540109 = 31540182
83 + 31540099 = 31540182
151 + 31540031 = 31540182
173 + 31540009 = 31540182
211 + 31539971 = 31540182
251 + 31539931 = 31540182

Showing the first eight; more decompositions exist.
