Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611352, here are decompositions:

11 + 31611341 = 31611352
23 + 31611329 = 31611352
29 + 31611323 = 31611352
41 + 31611311 = 31611352
53 + 31611299 = 31611352
239 + 31611113 = 31611352
251 + 31611101 = 31611352
263 + 31611089 = 31611352

Showing the first eight; more decompositions exist.
