Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486698, here are decompositions:

37 + 31486661 = 31486698
41 + 31486657 = 31486698
59 + 31486639 = 31486698
71 + 31486627 = 31486698
127 + 31486571 = 31486698
149 + 31486549 = 31486698
241 + 31486457 = 31486698
281 + 31486417 = 31486698

Showing the first eight; more decompositions exist.
