Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487992, here are decompositions:

19 + 33487973 = 33487992
23 + 33487969 = 33487992
79 + 33487913 = 33487992
89 + 33487903 = 33487992
173 + 33487819 = 33487992
179 + 33487813 = 33487992
233 + 33487759 = 33487992
311 + 33487681 = 33487992

Showing the first eight; more decompositions exist.
