Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518786, here are decompositions:

3 + 33518783 = 33518786
19 + 33518767 = 33518786
109 + 33518677 = 33518786
163 + 33518623 = 33518786
199 + 33518587 = 33518786
337 + 33518449 = 33518786
349 + 33518437 = 33518786
397 + 33518389 = 33518786

Showing the first eight; more decompositions exist.
