Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33491886, here are decompositions:

37 + 33491849 = 33491886
53 + 33491833 = 33491886
59 + 33491827 = 33491886
83 + 33491803 = 33491886
107 + 33491779 = 33491886
139 + 33491747 = 33491886
157 + 33491729 = 33491886
167 + 33491719 = 33491886

Showing the first eight; more decompositions exist.
