Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625604, here are decompositions:

5 + 31625599 = 31625604
37 + 31625567 = 31625604
41 + 31625563 = 31625604
67 + 31625537 = 31625604
97 + 31625507 = 31625604
137 + 31625467 = 31625604
151 + 31625453 = 31625604
173 + 31625431 = 31625604

Showing the first eight; more decompositions exist.
