Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468088, here are decompositions:

61 + 31468027 = 31468088
139 + 31467949 = 31468088
151 + 31467937 = 31468088
241 + 31467847 = 31468088
277 + 31467811 = 31468088
367 + 31467721 = 31468088
397 + 31467691 = 31468088
499 + 31467589 = 31468088

Showing the first eight; more decompositions exist.
