Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618872, here are decompositions:

19 + 33618853 = 33618872
103 + 33618769 = 33618872
229 + 33618643 = 33618872
379 + 33618493 = 33618872
421 + 33618451 = 33618872
433 + 33618439 = 33618872
541 + 33618331 = 33618872
673 + 33618199 = 33618872

Showing the first eight; more decompositions exist.
