Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495064, here are decompositions:

61 + 31495003 = 31495064
127 + 31494937 = 31495064
157 + 31494907 = 31495064
283 + 31494781 = 31495064
373 + 31494691 = 31495064
421 + 31494643 = 31495064
823 + 31494241 = 31495064
907 + 31494157 = 31495064

Showing the first eight; more decompositions exist.
