Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618380, here are decompositions:

67 + 33618313 = 33618380
73 + 33618307 = 33618380
181 + 33618199 = 33618380
241 + 33618139 = 33618380
277 + 33618103 = 33618380
349 + 33618031 = 33618380
373 + 33618007 = 33618380
379 + 33618001 = 33618380

Showing the first eight; more decompositions exist.
