Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478986, here are decompositions:

5 + 33478981 = 33478986
7 + 33478979 = 33478986
29 + 33478957 = 33478986
43 + 33478943 = 33478986
59 + 33478927 = 33478986
83 + 33478903 = 33478986
97 + 33478889 = 33478986
109 + 33478877 = 33478986

Showing the first eight; more decompositions exist.
