Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615096, here are decompositions:

83 + 31615013 = 31615096
89 + 31615007 = 31615096
167 + 31614929 = 31615096
197 + 31614899 = 31615096
257 + 31614839 = 31615096
263 + 31614833 = 31615096
389 + 31614707 = 31615096
419 + 31614677 = 31615096

Showing the first eight; more decompositions exist.
