Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523042, here are decompositions:

349 + 31522693 = 31523042
373 + 31522669 = 31523042
379 + 31522663 = 31523042
409 + 31522633 = 31523042
601 + 31522441 = 31523042
631 + 31522411 = 31523042
823 + 31522219 = 31523042
1021 + 31522021 = 31523042

Showing the first eight; more decompositions exist.
