Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625338, here are decompositions:

191 + 31625147 = 31625338
281 + 31625057 = 31625338
359 + 31624979 = 31625338
431 + 31624907 = 31625338
509 + 31624829 = 31625338
557 + 31624781 = 31625338
599 + 31624739 = 31625338
677 + 31624661 = 31625338

Showing the first eight; more decompositions exist.
