Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611342, here are decompositions:

13 + 31611329 = 31611342
19 + 31611323 = 31611342
23 + 31611319 = 31611342
31 + 31611311 = 31611342
41 + 31611301 = 31611342
43 + 31611299 = 31611342
71 + 31611271 = 31611342
179 + 31611163 = 31611342

Showing the first eight; more decompositions exist.
