Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499940, here are decompositions:

13 + 33499927 = 33499940
31 + 33499909 = 33499940
37 + 33499903 = 33499940
43 + 33499897 = 33499940
127 + 33499813 = 33499940
139 + 33499801 = 33499940
151 + 33499789 = 33499940
157 + 33499783 = 33499940

Showing the first eight; more decompositions exist.
