Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495088, here are decompositions:

109 + 31494979 = 31495088
139 + 31494949 = 31495088
151 + 31494937 = 31495088
181 + 31494907 = 31495088
271 + 31494817 = 31495088
307 + 31494781 = 31495088
367 + 31494721 = 31495088
397 + 31494691 = 31495088

Showing the first eight; more decompositions exist.
