Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559696, here are decompositions:

19 + 31559677 = 31559696
37 + 31559659 = 31559696
43 + 31559653 = 31559696
73 + 31559623 = 31559696
229 + 31559467 = 31559696
283 + 31559413 = 31559696
313 + 31559383 = 31559696
379 + 31559317 = 31559696

Showing the first eight; more decompositions exist.
