Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625284, here are decompositions:

3 + 31625281 = 31625284
23 + 31625261 = 31625284
137 + 31625147 = 31625284
227 + 31625057 = 31625284
503 + 31624781 = 31625284
521 + 31624763 = 31625284
641 + 31624643 = 31625284
653 + 31624631 = 31625284

Showing the first eight; more decompositions exist.
