Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542716, here are decompositions:

13 + 31542703 = 31542716
19 + 31542697 = 31542716
103 + 31542613 = 31542716
157 + 31542559 = 31542716
193 + 31542523 = 31542716
229 + 31542487 = 31542716
277 + 31542439 = 31542716
487 + 31542229 = 31542716

Showing the first eight; more decompositions exist.
