Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576098, here are decompositions:

7 + 31576091 = 31576098
11 + 31576087 = 31576098
31 + 31576067 = 31576098
61 + 31576037 = 31576098
67 + 31576031 = 31576098
89 + 31576009 = 31576098
97 + 31576001 = 31576098
107 + 31575991 = 31576098

Showing the first eight; more decompositions exist.
