Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522412, here are decompositions:

73 + 31522339 = 31522412
193 + 31522219 = 31522412
283 + 31522129 = 31522412
421 + 31521991 = 31522412
433 + 31521979 = 31522412
619 + 31521793 = 31522412
673 + 31521739 = 31522412
739 + 31521673 = 31522412

Showing the first eight; more decompositions exist.
