Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542662, here are decompositions:

3 + 31542659 = 31542662
31 + 31542631 = 31542662
103 + 31542559 = 31542662
139 + 31542523 = 31542662
223 + 31542439 = 31542662
271 + 31542391 = 31542662
433 + 31542229 = 31542662
499 + 31542163 = 31542662

Showing the first eight; more decompositions exist.
