Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33516640, here are decompositions:

107 + 33516533 = 33516640
149 + 33516491 = 33516640
191 + 33516449 = 33516640
233 + 33516407 = 33516640
347 + 33516293 = 33516640
389 + 33516251 = 33516640
503 + 33516137 = 33516640
719 + 33515921 = 33516640

Showing the first eight; more decompositions exist.
