Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626296, here are decompositions:

67 + 31626229 = 31626296
103 + 31626193 = 31626296
223 + 31626073 = 31626296
277 + 31626019 = 31626296
379 + 31625917 = 31626296
523 + 31625773 = 31626296
643 + 31625653 = 31626296
733 + 31625563 = 31626296

Showing the first eight; more decompositions exist.
