Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498528, here are decompositions:

11 + 31498517 = 31498528
29 + 31498499 = 31498528
59 + 31498469 = 31498528
101 + 31498427 = 31498528
107 + 31498421 = 31498528
179 + 31498349 = 31498528
239 + 31498289 = 31498528
251 + 31498277 = 31498528

Showing the first eight; more decompositions exist.
