Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559676, here are decompositions:

17 + 31559659 = 31559676
23 + 31559653 = 31559676
37 + 31559639 = 31559676
53 + 31559623 = 31559676
103 + 31559573 = 31559676
139 + 31559537 = 31559676
229 + 31559447 = 31559676
233 + 31559443 = 31559676

Showing the first eight; more decompositions exist.
