Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625462, here are decompositions:

31 + 31625431 = 31625462
61 + 31625401 = 31625462
79 + 31625383 = 31625462
181 + 31625281 = 31625462
199 + 31625263 = 31625462
283 + 31625179 = 31625462
313 + 31625149 = 31625462
331 + 31625131 = 31625462

Showing the first eight; more decompositions exist.
