Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623588, here are decompositions:

67 + 31623521 = 31623588
79 + 31623509 = 31623588
89 + 31623499 = 31623588
97 + 31623491 = 31623588
107 + 31623481 = 31623588
109 + 31623479 = 31623588
127 + 31623461 = 31623588
149 + 31623439 = 31623588

Showing the first eight; more decompositions exist.
