Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625342, here are decompositions:

61 + 31625281 = 31625342
79 + 31625263 = 31625342
163 + 31625179 = 31625342
193 + 31625149 = 31625342
211 + 31625131 = 31625342
283 + 31625059 = 31625342
421 + 31624921 = 31625342
601 + 31624741 = 31625342

Showing the first eight; more decompositions exist.
