Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537350, here are decompositions:

11 + 31537339 = 31537350
23 + 31537327 = 31537350
37 + 31537313 = 31537350
41 + 31537309 = 31537350
43 + 31537307 = 31537350
79 + 31537271 = 31537350
83 + 31537267 = 31537350
107 + 31537243 = 31537350

Showing the first eight; more decompositions exist.
