Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611396, here are decompositions:

17 + 31611379 = 31611396
29 + 31611367 = 31611396
67 + 31611329 = 31611396
73 + 31611323 = 31611396
97 + 31611299 = 31611396
233 + 31611163 = 31611396
269 + 31611127 = 31611396
283 + 31611113 = 31611396

Showing the first eight; more decompositions exist.
