Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625528, here are decompositions:

19 + 31625509 = 31625528
61 + 31625467 = 31625528
97 + 31625431 = 31625528
127 + 31625401 = 31625528
349 + 31625179 = 31625528
379 + 31625149 = 31625528
397 + 31625131 = 31625528
577 + 31624951 = 31625528

Showing the first eight; more decompositions exist.
