Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625382, here are decompositions:

31 + 31625351 = 31625382
79 + 31625303 = 31625382
101 + 31625281 = 31625382
233 + 31625149 = 31625382
251 + 31625131 = 31625382
431 + 31624951 = 31625382
443 + 31624939 = 31625382
461 + 31624921 = 31625382

Showing the first eight; more decompositions exist.
