Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495262, here are decompositions:

109 + 31495153 = 31495262
199 + 31495063 = 31495262
283 + 31494979 = 31495262
313 + 31494949 = 31495262
499 + 31494763 = 31495262
541 + 31494721 = 31495262
571 + 31494691 = 31495262
619 + 31494643 = 31495262

Showing the first eight; more decompositions exist.
