Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496122, here are decompositions:

3 + 31496119 = 31496122
23 + 31496099 = 31496122
173 + 31495949 = 31496122
263 + 31495859 = 31496122
389 + 31495733 = 31496122
431 + 31495691 = 31496122
461 + 31495661 = 31496122
521 + 31495601 = 31496122

Showing the first eight; more decompositions exist.
