Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33499890, here are decompositions:

7 + 33499883 = 33499890
43 + 33499847 = 33499890
89 + 33499801 = 33499890
101 + 33499789 = 33499890
107 + 33499783 = 33499890
113 + 33499777 = 33499890
131 + 33499759 = 33499890
139 + 33499751 = 33499890

Showing the first eight; more decompositions exist.
