Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463500, here are decompositions:

11 + 31463489 = 31463500
17 + 31463483 = 31463500
23 + 31463477 = 31463500
41 + 31463459 = 31463500
71 + 31463429 = 31463500
113 + 31463387 = 31463500
137 + 31463363 = 31463500
179 + 31463321 = 31463500

Showing the first eight; more decompositions exist.
