Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618778, here are decompositions:

5 + 33618773 = 33618778
29 + 33618749 = 33618778
41 + 33618737 = 33618778
59 + 33618719 = 33618778
107 + 33618671 = 33618778
419 + 33618359 = 33618778
449 + 33618329 = 33618778
461 + 33618317 = 33618778

Showing the first eight; more decompositions exist.
