Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498492, here are decompositions:

23 + 31498469 = 31498492
29 + 31498463 = 31498492
71 + 31498421 = 31498492
149 + 31498343 = 31498492
239 + 31498253 = 31498492
293 + 31498199 = 31498492
449 + 31498043 = 31498492
563 + 31497929 = 31498492

Showing the first eight; more decompositions exist.
