Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491812, here are decompositions:

71 + 33491741 = 33491812
83 + 33491729 = 33491812
131 + 33491681 = 33491812
173 + 33491639 = 33491812
191 + 33491621 = 33491812
251 + 33491561 = 33491812
269 + 33491543 = 33491812
353 + 33491459 = 33491812

Showing the first eight; more decompositions exist.
