Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615466, here are decompositions:

37 + 31615429 = 31615466
67 + 31615399 = 31615466
193 + 31615273 = 31615466
229 + 31615237 = 31615466
313 + 31615153 = 31615466
523 + 31614943 = 31615466
577 + 31614889 = 31615466
607 + 31614859 = 31615466

Showing the first eight; more decompositions exist.
