Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498522, here are decompositions:

5 + 31498517 = 31498522
23 + 31498499 = 31498522
53 + 31498469 = 31498522
59 + 31498463 = 31498522
101 + 31498421 = 31498522
173 + 31498349 = 31498522
179 + 31498343 = 31498522
233 + 31498289 = 31498522

Showing the first eight; more decompositions exist.
