Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524046, here are decompositions:

3 + 31524043 = 31524046
23 + 31524023 = 31524046
107 + 31523939 = 31524046
293 + 31523753 = 31524046
467 + 31523579 = 31524046
509 + 31523537 = 31524046
569 + 31523477 = 31524046
647 + 31523399 = 31524046

Showing the first eight; more decompositions exist.
