Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33616780, here are decompositions:

83 + 33616697 = 33616780
257 + 33616523 = 33616780
293 + 33616487 = 33616780
389 + 33616391 = 33616780
563 + 33616217 = 33616780
569 + 33616211 = 33616780
653 + 33616127 = 33616780
677 + 33616103 = 33616780

Showing the first eight; more decompositions exist.
