Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623962, here are decompositions:

3 + 31623959 = 31623962
31 + 31623931 = 31623962
61 + 31623901 = 31623962
241 + 31623721 = 31623962
373 + 31623589 = 31623962
439 + 31623523 = 31623962
463 + 31623499 = 31623962
523 + 31623439 = 31623962

Showing the first eight; more decompositions exist.
