Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614998, here are decompositions:

109 + 31614889 = 31614998
139 + 31614859 = 31614998
211 + 31614787 = 31614998
229 + 31614769 = 31614998
367 + 31614631 = 31614998
397 + 31614601 = 31614998
439 + 31614559 = 31614998
769 + 31614229 = 31614998

Showing the first eight; more decompositions exist.
