Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522124, here are decompositions:

103 + 31522021 = 31522124
241 + 31521883 = 31522124
331 + 31521793 = 31522124
457 + 31521667 = 31522124
643 + 31521481 = 31522124
691 + 31521433 = 31522124
853 + 31521271 = 31522124
967 + 31521157 = 31522124

Showing the first eight; more decompositions exist.
