Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498612, here are decompositions:

53 + 31498559 = 31498612
71 + 31498541 = 31498612
83 + 31498529 = 31498612
113 + 31498499 = 31498612
149 + 31498463 = 31498612
191 + 31498421 = 31498612
263 + 31498349 = 31498612
269 + 31498343 = 31498612

Showing the first eight; more decompositions exist.
