Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625408, here are decompositions:

7 + 31625401 = 31625408
127 + 31625281 = 31625408
229 + 31625179 = 31625408
277 + 31625131 = 31625408
349 + 31625059 = 31625408
457 + 31624951 = 31625408
487 + 31624921 = 31625408
547 + 31624861 = 31625408

Showing the first eight; more decompositions exist.
