Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475182, here are decompositions:

23 + 31475159 = 31475182
41 + 31475141 = 31475182
71 + 31475111 = 31475182
83 + 31475099 = 31475182
113 + 31475069 = 31475182
173 + 31475009 = 31475182
251 + 31474931 = 31475182
353 + 31474829 = 31475182

Showing the first eight; more decompositions exist.
