Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33549940, here are decompositions:

41 + 33549899 = 33549940
107 + 33549833 = 33549940
167 + 33549773 = 33549940
257 + 33549683 = 33549940
269 + 33549671 = 33549940
383 + 33549557 = 33549940
509 + 33549431 = 33549940
563 + 33549377 = 33549940

Showing the first eight; more decompositions exist.
