Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532814, here are decompositions:

37 + 31532777 = 31532814
127 + 31532687 = 31532814
227 + 31532587 = 31532814
233 + 31532581 = 31532814
241 + 31532573 = 31532814
263 + 31532551 = 31532814
293 + 31532521 = 31532814
307 + 31532507 = 31532814

Showing the first eight; more decompositions exist.
