Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564840, here are decompositions:

73 + 33564767 = 33564840
79 + 33564761 = 33564840
83 + 33564757 = 33564840
103 + 33564737 = 33564840
109 + 33564731 = 33564840
163 + 33564677 = 33564840
167 + 33564673 = 33564840
349 + 33564491 = 33564840

Showing the first eight; more decompositions exist.
