Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542436, here are decompositions:

17 + 31542419 = 31542436
59 + 31542377 = 31542436
113 + 31542323 = 31542436
239 + 31542197 = 31542436
353 + 31542083 = 31542436
503 + 31541933 = 31542436
743 + 31541693 = 31542436
839 + 31541597 = 31542436

Showing the first eight; more decompositions exist.
