Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611354, here are decompositions:

13 + 31611341 = 31611354
31 + 31611323 = 31611354
43 + 31611311 = 31611354
53 + 31611301 = 31611354
83 + 31611271 = 31611354
167 + 31611187 = 31611354
191 + 31611163 = 31611354
227 + 31611127 = 31611354

Showing the first eight; more decompositions exist.
