Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510676, here are decompositions:

19 + 31510657 = 31510676
73 + 31510603 = 31510676
103 + 31510573 = 31510676
229 + 31510447 = 31510676
277 + 31510399 = 31510676
313 + 31510363 = 31510676
367 + 31510309 = 31510676
433 + 31510243 = 31510676

Showing the first eight; more decompositions exist.
