Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623758, here are decompositions:

37 + 31623721 = 31623758
151 + 31623607 = 31623758
277 + 31623481 = 31623758
337 + 31623421 = 31623758
421 + 31623337 = 31623758
547 + 31623211 = 31623758
577 + 31623181 = 31623758
811 + 31622947 = 31623758

Showing the first eight; more decompositions exist.
