Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498862, here are decompositions:

13 + 31498849 = 31498862
223 + 31498639 = 31498862
271 + 31498591 = 31498862
313 + 31498549 = 31498862
349 + 31498513 = 31498862
673 + 31498189 = 31498862
739 + 31498123 = 31498862
751 + 31498111 = 31498862

Showing the first eight; more decompositions exist.
