Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535724, here are decompositions:

7 + 31535717 = 31535724
43 + 31535681 = 31535724
53 + 31535671 = 31535724
67 + 31535657 = 31535724
131 + 31535593 = 31535724
173 + 31535551 = 31535724
257 + 31535467 = 31535724
307 + 31535417 = 31535724

Showing the first eight; more decompositions exist.
