Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534744, here are decompositions:

5 + 31534739 = 31534744
53 + 31534691 = 31534744
107 + 31534637 = 31534744
113 + 31534631 = 31534744
191 + 31534553 = 31534744
251 + 31534493 = 31534744
257 + 31534487 = 31534744
317 + 31534427 = 31534744

Showing the first eight; more decompositions exist.
