Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532630, here are decompositions:

37 + 31532593 = 31532630
43 + 31532587 = 31532630
79 + 31532551 = 31532630
109 + 31532521 = 31532630
193 + 31532437 = 31532630
229 + 31532401 = 31532630
277 + 31532353 = 31532630
307 + 31532323 = 31532630

Showing the first eight; more decompositions exist.
