Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623534, here are decompositions:

11 + 31623523 = 31623534
13 + 31623521 = 31623534
23 + 31623511 = 31623534
37 + 31623497 = 31623534
43 + 31623491 = 31623534
53 + 31623481 = 31623534
73 + 31623461 = 31623534
113 + 31623421 = 31623534

Showing the first eight; more decompositions exist.
