Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528514, here are decompositions:

13 + 31528501 = 31528514
67 + 31528447 = 31528514
151 + 31528363 = 31528514
223 + 31528291 = 31528514
307 + 31528207 = 31528514
421 + 31528093 = 31528514
547 + 31527967 = 31528514
601 + 31527913 = 31528514

Showing the first eight; more decompositions exist.
