Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625556, here are decompositions:

19 + 31625537 = 31625556
47 + 31625509 = 31625556
89 + 31625467 = 31625556
103 + 31625453 = 31625556
163 + 31625393 = 31625556
173 + 31625383 = 31625556
293 + 31625263 = 31625556
409 + 31625147 = 31625556

Showing the first eight; more decompositions exist.
