Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537602, here are decompositions:

11 + 31537591 = 31537602
29 + 31537573 = 31537602
43 + 31537559 = 31537602
59 + 31537543 = 31537602
193 + 31537409 = 31537602
211 + 31537391 = 31537602
263 + 31537339 = 31537602
293 + 31537309 = 31537602

Showing the first eight; more decompositions exist.
