Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568694, here are decompositions:

37 + 31568657 = 31568694
83 + 31568611 = 31568694
107 + 31568587 = 31568694
151 + 31568543 = 31568694
167 + 31568527 = 31568694
197 + 31568497 = 31568694
271 + 31568423 = 31568694
277 + 31568417 = 31568694

Showing the first eight; more decompositions exist.
