Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33562640, here are decompositions:

31 + 33562609 = 33562640
127 + 33562513 = 33562640
229 + 33562411 = 33562640
367 + 33562273 = 33562640
487 + 33562153 = 33562640
607 + 33562033 = 33562640
613 + 33562027 = 33562640
691 + 33561949 = 33562640

Showing the first eight; more decompositions exist.
