Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491668, here are decompositions:

29 + 33491639 = 33491668
47 + 33491621 = 33491668
101 + 33491567 = 33491668
107 + 33491561 = 33491668
131 + 33491537 = 33491668
179 + 33491489 = 33491668
227 + 33491441 = 33491668
251 + 33491417 = 33491668

Showing the first eight; more decompositions exist.
