Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450088, here are decompositions:

31 + 31450057 = 31450088
67 + 31450021 = 31450088
97 + 31449991 = 31450088
151 + 31449937 = 31450088
157 + 31449931 = 31450088
331 + 31449757 = 31450088
337 + 31449751 = 31450088
349 + 31449739 = 31450088

Showing the first eight; more decompositions exist.
