Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490696, here are decompositions:

19 + 31490677 = 31490696
37 + 31490659 = 31490696
67 + 31490629 = 31490696
73 + 31490623 = 31490696
103 + 31490593 = 31490696
109 + 31490587 = 31490696
199 + 31490497 = 31490696
313 + 31490383 = 31490696

Showing the first eight; more decompositions exist.
