Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495034, here are decompositions:

31 + 31495003 = 31495034
97 + 31494937 = 31495034
127 + 31494907 = 31495034
271 + 31494763 = 31495034
313 + 31494721 = 31495034
397 + 31494637 = 31495034
607 + 31494427 = 31495034
733 + 31494301 = 31495034

Showing the first eight; more decompositions exist.
