Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623470, here are decompositions:

31 + 31623439 = 31623470
97 + 31623373 = 31623470
127 + 31623343 = 31623470
271 + 31623199 = 31623470
349 + 31623121 = 31623470
409 + 31623061 = 31623470
523 + 31622947 = 31623470
547 + 31622923 = 31623470

Showing the first eight; more decompositions exist.
