Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537984, here are decompositions:

3 + 31537981 = 31537984
113 + 31537871 = 31537984
263 + 31537721 = 31537984
293 + 31537691 = 31537984
353 + 31537631 = 31537984
503 + 31537481 = 31537984
593 + 31537391 = 31537984
677 + 31537307 = 31537984

Showing the first eight; more decompositions exist.
