Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498374, here are decompositions:

7 + 31498367 = 31498374
31 + 31498343 = 31498374
67 + 31498307 = 31498374
97 + 31498277 = 31498374
101 + 31498273 = 31498374
157 + 31498217 = 31498374
181 + 31498193 = 31498374
223 + 31498151 = 31498374

Showing the first eight; more decompositions exist.
