Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567492, here are decompositions:

41 + 31567451 = 31567492
179 + 31567313 = 31567492
251 + 31567241 = 31567492
401 + 31567091 = 31567492
443 + 31567049 = 31567492
449 + 31567043 = 31567492
653 + 31566839 = 31567492
743 + 31566749 = 31567492

Showing the first eight; more decompositions exist.
