Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615382, here are decompositions:

61 + 31615321 = 31615382
109 + 31615273 = 31615382
229 + 31615153 = 31615382
439 + 31614943 = 31615382
523 + 31614859 = 31615382
613 + 31614769 = 31615382
739 + 31614643 = 31615382
751 + 31614631 = 31615382

Showing the first eight; more decompositions exist.
