Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465624, here are decompositions:

5 + 31465619 = 31465624
23 + 31465601 = 31465624
53 + 31465571 = 31465624
173 + 31465451 = 31465624
233 + 31465391 = 31465624
401 + 31465223 = 31465624
431 + 31465193 = 31465624
563 + 31465061 = 31465624

Showing the first eight; more decompositions exist.
