Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625326, here are decompositions:

23 + 31625303 = 31625326
179 + 31625147 = 31625326
269 + 31625057 = 31625326
347 + 31624979 = 31625326
419 + 31624907 = 31625326
563 + 31624763 = 31625326
587 + 31624739 = 31625326
653 + 31624673 = 31625326

Showing the first eight; more decompositions exist.
