Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463562, here are decompositions:

29 + 31463533 = 31463562
43 + 31463519 = 31463562
73 + 31463489 = 31463562
79 + 31463483 = 31463562
103 + 31463459 = 31463562
173 + 31463389 = 31463562
199 + 31463363 = 31463562
233 + 31463329 = 31463562

Showing the first eight; more decompositions exist.
