Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622348, here are decompositions:

61 + 31622287 = 31622348
67 + 31622281 = 31622348
181 + 31622167 = 31622348
229 + 31622119 = 31622348
367 + 31621981 = 31622348
727 + 31621621 = 31622348
757 + 31621591 = 31622348
787 + 31621561 = 31622348

Showing the first eight; more decompositions exist.
