Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542596, here are decompositions:

37 + 31542559 = 31542596
73 + 31542523 = 31542596
109 + 31542487 = 31542596
139 + 31542457 = 31542596
157 + 31542439 = 31542596
199 + 31542397 = 31542596
223 + 31542373 = 31542596
367 + 31542229 = 31542596

Showing the first eight; more decompositions exist.
