Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498582, here are decompositions:

23 + 31498559 = 31498582
41 + 31498541 = 31498582
53 + 31498529 = 31498582
83 + 31498499 = 31498582
113 + 31498469 = 31498582
233 + 31498349 = 31498582
239 + 31498343 = 31498582
293 + 31498289 = 31498582

Showing the first eight; more decompositions exist.
