Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625534, here are decompositions:

67 + 31625467 = 31625534
103 + 31625431 = 31625534
151 + 31625383 = 31625534
271 + 31625263 = 31625534
607 + 31624927 = 31625534
613 + 31624921 = 31625534
673 + 31624861 = 31625534
727 + 31624807 = 31625534

Showing the first eight; more decompositions exist.
