Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33608778, here are decompositions:

41 + 33608737 = 33608778
59 + 33608719 = 33608778
61 + 33608717 = 33608778
131 + 33608647 = 33608778
139 + 33608639 = 33608778
149 + 33608629 = 33608778
167 + 33608611 = 33608778
197 + 33608581 = 33608778

Showing the first eight; more decompositions exist.
