Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623558, here are decompositions:

37 + 31623521 = 31623558
47 + 31623511 = 31623558
59 + 31623499 = 31623558
61 + 31623497 = 31623558
67 + 31623491 = 31623558
79 + 31623479 = 31623558
97 + 31623461 = 31623558
137 + 31623421 = 31623558

Showing the first eight; more decompositions exist.
