Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487986, here are decompositions:

13 + 33487973 = 33487986
17 + 33487969 = 33487986
73 + 33487913 = 33487986
79 + 33487907 = 33487986
83 + 33487903 = 33487986
109 + 33487877 = 33487986
127 + 33487859 = 33487986
139 + 33487847 = 33487986

Showing the first eight; more decompositions exist.
