Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615872, here are decompositions:

19 + 33615853 = 33615872
79 + 33615793 = 33615872
211 + 33615661 = 33615872
223 + 33615649 = 33615872
229 + 33615643 = 33615872
271 + 33615601 = 33615872
349 + 33615523 = 33615872
379 + 33615493 = 33615872

Showing the first eight; more decompositions exist.
