Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569684, here are decompositions:

37 + 31569647 = 31569684
43 + 31569641 = 31569684
67 + 31569617 = 31569684
71 + 31569613 = 31569684
103 + 31569581 = 31569684
193 + 31569491 = 31569684
317 + 31569367 = 31569684
337 + 31569347 = 31569684

Showing the first eight; more decompositions exist.
