Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498682, here are decompositions:

43 + 31498639 = 31498682
211 + 31498471 = 31498682
409 + 31498273 = 31498682
571 + 31498111 = 31498682
613 + 31498069 = 31498682
643 + 31498039 = 31498682
673 + 31498009 = 31498682
751 + 31497931 = 31498682

Showing the first eight; more decompositions exist.
