Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498216, here are decompositions:

3 + 31498213 = 31498216
17 + 31498199 = 31498216
23 + 31498193 = 31498216
173 + 31498043 = 31498216
353 + 31497863 = 31498216
389 + 31497827 = 31498216
419 + 31497797 = 31498216
443 + 31497773 = 31498216

Showing the first eight; more decompositions exist.
