Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618020, here are decompositions:

13 + 33618007 = 33618020
19 + 33618001 = 33618020
157 + 33617863 = 33618020
223 + 33617797 = 33618020
409 + 33617611 = 33618020
421 + 33617599 = 33618020
463 + 33617557 = 33618020
607 + 33617413 = 33618020

Showing the first eight; more decompositions exist.
