Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625576, here are decompositions:

13 + 31625563 = 31625576
67 + 31625509 = 31625576
109 + 31625467 = 31625576
193 + 31625383 = 31625576
313 + 31625263 = 31625576
397 + 31625179 = 31625576
727 + 31624849 = 31625576
739 + 31624837 = 31625576

Showing the first eight; more decompositions exist.
