Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611698, here are decompositions:

31 + 31611667 = 31611698
211 + 31611487 = 31611698
241 + 31611457 = 31611698
331 + 31611367 = 31611698
379 + 31611319 = 31611698
397 + 31611301 = 31611698
571 + 31611127 = 31611698
631 + 31611067 = 31611698

Showing the first eight; more decompositions exist.
