Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576110, here are decompositions:

19 + 31576091 = 31576110
23 + 31576087 = 31576110
43 + 31576067 = 31576110
61 + 31576049 = 31576110
73 + 31576037 = 31576110
79 + 31576031 = 31576110
101 + 31576009 = 31576110
103 + 31576007 = 31576110

Showing the first eight; more decompositions exist.
