Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623166, here are decompositions:

53 + 31623113 = 31623166
227 + 31622939 = 31623166
233 + 31622933 = 31623166
389 + 31622777 = 31623166
467 + 31622699 = 31623166
479 + 31622687 = 31623166
503 + 31622663 = 31623166
587 + 31622579 = 31623166

Showing the first eight; more decompositions exist.
