Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494996, here are decompositions:

17 + 31494979 = 31494996
47 + 31494949 = 31494996
53 + 31494943 = 31494996
59 + 31494937 = 31494996
73 + 31494923 = 31494996
89 + 31494907 = 31494996
109 + 31494887 = 31494996
179 + 31494817 = 31494996

Showing the first eight; more decompositions exist.
