Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614240, here are decompositions:

11 + 31614229 = 31614240
13 + 31614227 = 31614240
23 + 31614217 = 31614240
29 + 31614211 = 31614240
41 + 31614199 = 31614240
43 + 31614197 = 31614240
59 + 31614181 = 31614240
61 + 31614179 = 31614240

Showing the first eight; more decompositions exist.
