Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498486, here are decompositions:

17 + 31498469 = 31498486
23 + 31498463 = 31498486
59 + 31498427 = 31498486
137 + 31498349 = 31498486
179 + 31498307 = 31498486
197 + 31498289 = 31498486
233 + 31498253 = 31498486
269 + 31498217 = 31498486

Showing the first eight; more decompositions exist.
