Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623418, here are decompositions:

41 + 31623377 = 31623418
251 + 31623167 = 31623418
467 + 31622951 = 31623418
479 + 31622939 = 31623418
641 + 31622777 = 31623418
677 + 31622741 = 31623418
719 + 31622699 = 31623418
839 + 31622579 = 31623418

Showing the first eight; more decompositions exist.
