Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532624, here are decompositions:

31 + 31532593 = 31532624
37 + 31532587 = 31532624
43 + 31532581 = 31532624
73 + 31532551 = 31532624
103 + 31532521 = 31532624
127 + 31532497 = 31532624
223 + 31532401 = 31532624
271 + 31532353 = 31532624

Showing the first eight; more decompositions exist.
