Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625532, here are decompositions:

23 + 31625509 = 31625532
79 + 31625453 = 31625532
101 + 31625431 = 31625532
131 + 31625401 = 31625532
139 + 31625393 = 31625532
149 + 31625383 = 31625532
151 + 31625381 = 31625532
181 + 31625351 = 31625532

Showing the first eight; more decompositions exist.
