Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523640, here are decompositions:

61 + 33523579 = 33523640
193 + 33523447 = 33523640
229 + 33523411 = 33523640
313 + 33523327 = 33523640
349 + 33523291 = 33523640
379 + 33523261 = 33523640
421 + 33523219 = 33523640
499 + 33523141 = 33523640

Showing the first eight; more decompositions exist.
