Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463502, here are decompositions:

13 + 31463489 = 31463502
19 + 31463483 = 31463502
43 + 31463459 = 31463502
73 + 31463429 = 31463502
113 + 31463389 = 31463502
139 + 31463363 = 31463502
149 + 31463353 = 31463502
173 + 31463329 = 31463502

Showing the first eight; more decompositions exist.
