Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475702, here are decompositions:

19 + 31475683 = 31475702
79 + 31475623 = 31475702
103 + 31475599 = 31475702
211 + 31475491 = 31475702
331 + 31475371 = 31475702
571 + 31475131 = 31475702
613 + 31475089 = 31475702
619 + 31475083 = 31475702

Showing the first eight; more decompositions exist.
