Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490364, here are decompositions:

5 + 31490359 = 31490364
13 + 31490351 = 31490364
41 + 31490323 = 31490364
67 + 31490297 = 31490364
83 + 31490281 = 31490364
107 + 31490257 = 31490364
127 + 31490237 = 31490364
137 + 31490227 = 31490364

Showing the first eight; more decompositions exist.
