Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611416, here are decompositions:

13 + 31611403 = 31611416
37 + 31611379 = 31611416
97 + 31611319 = 31611416
229 + 31611187 = 31611416
349 + 31611067 = 31611416
367 + 31611049 = 31611416
373 + 31611043 = 31611416
379 + 31611037 = 31611416

Showing the first eight; more decompositions exist.
