Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623352, here are decompositions:

179 + 31623173 = 31623352
239 + 31623113 = 31623352
311 + 31623041 = 31623352
401 + 31622951 = 31623352
419 + 31622933 = 31623352
653 + 31622699 = 31623352
659 + 31622693 = 31623352
773 + 31622579 = 31623352

Showing the first eight; more decompositions exist.
