Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626032, here are decompositions:

13 + 31626019 = 31626032
79 + 31625953 = 31626032
211 + 31625821 = 31626032
271 + 31625761 = 31626032
379 + 31625653 = 31626032
433 + 31625599 = 31626032
523 + 31625509 = 31626032
601 + 31625431 = 31626032

Showing the first eight; more decompositions exist.
