Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625570, here are decompositions:

3 + 31625567 = 31625570
7 + 31625563 = 31625570
61 + 31625509 = 31625570
103 + 31625467 = 31625570
139 + 31625431 = 31625570
307 + 31625263 = 31625570
421 + 31625149 = 31625570
439 + 31625131 = 31625570

Showing the first eight; more decompositions exist.
