Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558264, here are decompositions:

11 + 31558253 = 31558264
41 + 31558223 = 31558264
53 + 31558211 = 31558264
83 + 31558181 = 31558264
131 + 31558133 = 31558264
137 + 31558127 = 31558264
191 + 31558073 = 31558264
251 + 31558013 = 31558264

Showing the first eight; more decompositions exist.
