Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625176, here are decompositions:

29 + 31625147 = 31625176
137 + 31625039 = 31625176
197 + 31624979 = 31625176
269 + 31624907 = 31625176
347 + 31624829 = 31625176
503 + 31624673 = 31625176
563 + 31624613 = 31625176
617 + 31624559 = 31625176

Showing the first eight; more decompositions exist.
