Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618940, here are decompositions:

53 + 33618887 = 33618940
83 + 33618857 = 33618940
101 + 33618839 = 33618940
167 + 33618773 = 33618940
191 + 33618749 = 33618940
269 + 33618671 = 33618940
449 + 33618491 = 33618940
617 + 33618323 = 33618940

Showing the first eight; more decompositions exist.
