Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532684, here are decompositions:

31 + 31532653 = 31532684
97 + 31532587 = 31532684
103 + 31532581 = 31532684
163 + 31532521 = 31532684
283 + 31532401 = 31532684
331 + 31532353 = 31532684
457 + 31532227 = 31532684
571 + 31532113 = 31532684

Showing the first eight; more decompositions exist.
