Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620864, here are decompositions:

7 + 33620857 = 33620864
61 + 33620803 = 33620864
97 + 33620767 = 33620864
103 + 33620761 = 33620864
157 + 33620707 = 33620864
241 + 33620623 = 33620864
271 + 33620593 = 33620864
337 + 33620527 = 33620864

Showing the first eight; more decompositions exist.
