Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626164, here are decompositions:

211 + 31625953 = 31626164
397 + 31625767 = 31626164
433 + 31625731 = 31626164
547 + 31625617 = 31626164
601 + 31625563 = 31626164
733 + 31625431 = 31626164
883 + 31625281 = 31626164
1033 + 31625131 = 31626164

Showing the first eight; more decompositions exist.
