Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625876, here are decompositions:

97 + 31625779 = 31625876
103 + 31625773 = 31625876
109 + 31625767 = 31625876
223 + 31625653 = 31625876
229 + 31625647 = 31625876
277 + 31625599 = 31625876
313 + 31625563 = 31625876
367 + 31625509 = 31625876

Showing the first eight; more decompositions exist.
