Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542962, here are decompositions:

13 + 31542949 = 31542962
19 + 31542943 = 31542962
151 + 31542811 = 31542962
163 + 31542799 = 31542962
331 + 31542631 = 31542962
349 + 31542613 = 31542962
439 + 31542523 = 31542962
523 + 31542439 = 31542962

Showing the first eight; more decompositions exist.
