Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498748, here are decompositions:

7 + 31498741 = 31498748
109 + 31498639 = 31498748
157 + 31498591 = 31498748
199 + 31498549 = 31498748
277 + 31498471 = 31498748
661 + 31498087 = 31498748
709 + 31498039 = 31498748
739 + 31498009 = 31498748

Showing the first eight; more decompositions exist.
