Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463974, here are decompositions:

11 + 31463963 = 31463974
53 + 31463921 = 31463974
83 + 31463891 = 31463974
131 + 31463843 = 31463974
167 + 31463807 = 31463974
257 + 31463717 = 31463974
293 + 31463681 = 31463974
383 + 31463591 = 31463974

Showing the first eight; more decompositions exist.
