Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463790, here are decompositions:

11 + 31463779 = 31463790
23 + 31463767 = 31463790
31 + 31463759 = 31463790
47 + 31463743 = 31463790
73 + 31463717 = 31463790
101 + 31463689 = 31463790
109 + 31463681 = 31463790
199 + 31463591 = 31463790

Showing the first eight; more decompositions exist.
