Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625606, here are decompositions:

3 + 31625603 = 31625606
7 + 31625599 = 31625606
43 + 31625563 = 31625606
97 + 31625509 = 31625606
139 + 31625467 = 31625606
223 + 31625383 = 31625606
457 + 31625149 = 31625606
547 + 31625059 = 31625606

Showing the first eight; more decompositions exist.
