Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561686, here are decompositions:

7 + 33561679 = 33561686
13 + 33561673 = 33561686
79 + 33561607 = 33561686
127 + 33561559 = 33561686
307 + 33561379 = 33561686
547 + 33561139 = 33561686
607 + 33561079 = 33561686
619 + 33561067 = 33561686

Showing the first eight; more decompositions exist.
