Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540088, here are decompositions:

79 + 31540009 = 31540088
157 + 31539931 = 31540088
199 + 31539889 = 31540088
271 + 31539817 = 31540088
331 + 31539757 = 31540088
439 + 31539649 = 31540088
739 + 31539349 = 31540088
751 + 31539337 = 31540088

Showing the first eight; more decompositions exist.
