Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491786, here are decompositions:

7 + 33491779 = 33491786
19 + 33491767 = 33491786
67 + 33491719 = 33491786
73 + 33491713 = 33491786
193 + 33491593 = 33491786
787 + 33490999 = 33491786
859 + 33490927 = 33491786
1009 + 33490777 = 33491786

Showing the first eight; more decompositions exist.
