Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524142, here are decompositions:

131 + 31524011 = 31524142
389 + 31523753 = 31524142
491 + 31523651 = 31524142
509 + 31523633 = 31524142
563 + 31523579 = 31524142
701 + 31523441 = 31524142
743 + 31523399 = 31524142
761 + 31523381 = 31524142

Showing the first eight; more decompositions exist.
