Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451496, here are decompositions:

5 + 31451491 = 31451496
7 + 31451489 = 31451496
59 + 31451437 = 31451496
113 + 31451383 = 31451496
149 + 31451347 = 31451496
173 + 31451323 = 31451496
199 + 31451297 = 31451496
227 + 31451269 = 31451496

Showing the first eight; more decompositions exist.
