Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558336, here are decompositions:

53 + 31558283 = 31558336
83 + 31558253 = 31558336
107 + 31558229 = 31558336
113 + 31558223 = 31558336
137 + 31558199 = 31558336
149 + 31558187 = 31558336
167 + 31558169 = 31558336
263 + 31558073 = 31558336

Showing the first eight; more decompositions exist.
