Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537326, here are decompositions:

13 + 31537313 = 31537326
17 + 31537309 = 31537326
19 + 31537307 = 31537326
53 + 31537273 = 31537326
59 + 31537267 = 31537326
83 + 31537243 = 31537326
97 + 31537229 = 31537326
103 + 31537223 = 31537326

Showing the first eight; more decompositions exist.
