Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558416, here are decompositions:

17 + 31558399 = 31558416
37 + 31558379 = 31558416
79 + 31558337 = 31558416
89 + 31558327 = 31558416
107 + 31558309 = 31558416
163 + 31558253 = 31558416
193 + 31558223 = 31558416
229 + 31558187 = 31558416

Showing the first eight; more decompositions exist.
