Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492352, here are decompositions:

109 + 31492243 = 31492352
139 + 31492213 = 31492352
271 + 31492081 = 31492352
439 + 31491913 = 31492352
673 + 31491679 = 31492352
691 + 31491661 = 31492352
733 + 31491619 = 31492352
739 + 31491613 = 31492352

Showing the first eight; more decompositions exist.
