Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487236, here are decompositions:

17 + 33487219 = 33487236
43 + 33487193 = 33487236
47 + 33487189 = 33487236
73 + 33487163 = 33487236
89 + 33487147 = 33487236
239 + 33486997 = 33487236
283 + 33486953 = 33487236
373 + 33486863 = 33487236

Showing the first eight; more decompositions exist.
