Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495052, here are decompositions:

73 + 31494979 = 31495052
103 + 31494949 = 31495052
109 + 31494943 = 31495052
271 + 31494781 = 31495052
283 + 31494769 = 31495052
331 + 31494721 = 31495052
373 + 31494679 = 31495052
409 + 31494643 = 31495052

Showing the first eight; more decompositions exist.
