Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498488, here are decompositions:

17 + 31498471 = 31498488
19 + 31498469 = 31498488
61 + 31498427 = 31498488
67 + 31498421 = 31498488
139 + 31498349 = 31498488
181 + 31498307 = 31498488
199 + 31498289 = 31498488
211 + 31498277 = 31498488

Showing the first eight; more decompositions exist.
