Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33500640, here are decompositions:

23 + 33500617 = 33500640
53 + 33500587 = 33500640
67 + 33500573 = 33500640
127 + 33500513 = 33500640
139 + 33500501 = 33500640
179 + 33500461 = 33500640
181 + 33500459 = 33500640
191 + 33500449 = 33500640

Showing the first eight; more decompositions exist.
