Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567682, here are decompositions:

61 + 31567621 = 31567682
79 + 31567603 = 31567682
271 + 31567411 = 31567682
313 + 31567369 = 31567682
463 + 31567219 = 31567682
709 + 31566973 = 31567682
919 + 31566763 = 31567682
1051 + 31566631 = 31567682

Showing the first eight; more decompositions exist.
