Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494206, here are decompositions:

109 + 31494097 = 31494206
127 + 31494079 = 31494206
223 + 31493983 = 31494206
307 + 31493899 = 31494206
349 + 31493857 = 31494206
463 + 31493743 = 31494206
607 + 31493599 = 31494206
613 + 31493593 = 31494206

Showing the first eight; more decompositions exist.
