Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491810, here are decompositions:

7 + 33491803 = 33491810
31 + 33491779 = 33491810
43 + 33491767 = 33491810
97 + 33491713 = 33491810
139 + 33491671 = 33491810
211 + 33491599 = 33491810
241 + 33491569 = 33491810
277 + 33491533 = 33491810

Showing the first eight; more decompositions exist.
