Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623262, here are decompositions:

5 + 31623257 = 31623262
53 + 31623209 = 31623262
89 + 31623173 = 31623262
149 + 31623113 = 31623262
239 + 31623023 = 31623262
311 + 31622951 = 31623262
521 + 31622741 = 31623262
563 + 31622699 = 31623262

Showing the first eight; more decompositions exist.
