Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623848, here are decompositions:

31 + 31623817 = 31623848
127 + 31623721 = 31623848
181 + 31623667 = 31623848
241 + 31623607 = 31623848
337 + 31623511 = 31623848
349 + 31623499 = 31623848
367 + 31623481 = 31623848
409 + 31623439 = 31623848

Showing the first eight; more decompositions exist.
