Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447596, here are decompositions:

13 + 31447583 = 31447596
23 + 31447573 = 31447596
67 + 31447529 = 31447596
109 + 31447487 = 31447596
139 + 31447457 = 31447596
157 + 31447439 = 31447596
233 + 31447363 = 31447596
239 + 31447357 = 31447596

Showing the first eight; more decompositions exist.
