Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626200, here are decompositions:

3 + 31626197 = 31626200
7 + 31626193 = 31626200
127 + 31626073 = 31626200
181 + 31626019 = 31626200
283 + 31625917 = 31626200
379 + 31625821 = 31626200
421 + 31625779 = 31626200
433 + 31625767 = 31626200

Showing the first eight; more decompositions exist.
