Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542796, here are decompositions:

29 + 31542767 = 31542796
137 + 31542659 = 31542796
317 + 31542479 = 31542796
359 + 31542437 = 31542796
419 + 31542377 = 31542796
563 + 31542233 = 31542796
599 + 31542197 = 31542796
647 + 31542149 = 31542796

Showing the first eight; more decompositions exist.
