Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581072, here are decompositions:

61 + 33581011 = 33581072
79 + 33580993 = 33581072
163 + 33580909 = 33581072
181 + 33580891 = 33581072
193 + 33580879 = 33581072
223 + 33580849 = 33581072
271 + 33580801 = 33581072
331 + 33580741 = 33581072

Showing the first eight; more decompositions exist.
