Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625938, here are decompositions:

89 + 31625849 = 31625938
131 + 31625807 = 31625938
257 + 31625681 = 31625938
359 + 31625579 = 31625938
401 + 31625537 = 31625938
431 + 31625507 = 31625938
557 + 31625381 = 31625938
587 + 31625351 = 31625938

Showing the first eight; more decompositions exist.
