Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537336, here are decompositions:

23 + 31537313 = 31537336
29 + 31537307 = 31537336
107 + 31537229 = 31537336
113 + 31537223 = 31537336
239 + 31537097 = 31537336
293 + 31537043 = 31537336
353 + 31536983 = 31537336
419 + 31536917 = 31537336

Showing the first eight; more decompositions exist.
