Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611674, here are decompositions:

7 + 31611667 = 31611674
67 + 31611607 = 31611674
97 + 31611577 = 31611674
271 + 31611403 = 31611674
307 + 31611367 = 31611674
373 + 31611301 = 31611674
487 + 31611187 = 31611674
547 + 31611127 = 31611674

Showing the first eight; more decompositions exist.
