Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498792, here are decompositions:

29 + 31498763 = 31498792
89 + 31498703 = 31498792
233 + 31498559 = 31498792
251 + 31498541 = 31498792
263 + 31498529 = 31498792
293 + 31498499 = 31498792
443 + 31498349 = 31498792
449 + 31498343 = 31498792

Showing the first eight; more decompositions exist.
