Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498314, here are decompositions:

7 + 31498307 = 31498314
37 + 31498277 = 31498314
41 + 31498273 = 31498314
61 + 31498253 = 31498314
97 + 31498217 = 31498314
101 + 31498213 = 31498314
163 + 31498151 = 31498314
191 + 31498123 = 31498314

Showing the first eight; more decompositions exist.
