Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611232, here are decompositions:

131 + 31611101 = 31611232
461 + 31610771 = 31611232
491 + 31610741 = 31611232
503 + 31610729 = 31611232
509 + 31610723 = 31611232
593 + 31610639 = 31611232
659 + 31610573 = 31611232
839 + 31610393 = 31611232

Showing the first eight; more decompositions exist.
