Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33527640, here are decompositions:

23 + 33527617 = 33527640
37 + 33527603 = 33527640
43 + 33527597 = 33527640
101 + 33527539 = 33527640
109 + 33527531 = 33527640
151 + 33527489 = 33527640
173 + 33527467 = 33527640
193 + 33527447 = 33527640

Showing the first eight; more decompositions exist.
