Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623336, here are decompositions:

79 + 31623257 = 31623336
113 + 31623223 = 31623336
127 + 31623209 = 31623336
137 + 31623199 = 31623336
163 + 31623173 = 31623336
167 + 31623169 = 31623336
223 + 31623113 = 31623336
313 + 31623023 = 31623336

Showing the first eight; more decompositions exist.
