Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615022, here are decompositions:

79 + 31614943 = 31615022
163 + 31614859 = 31615022
193 + 31614829 = 31615022
379 + 31614643 = 31615022
421 + 31614601 = 31615022
463 + 31614559 = 31615022
499 + 31614523 = 31615022
739 + 31614283 = 31615022

Showing the first eight; more decompositions exist.
