Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487770, here are decompositions:

11 + 33487759 = 33487770
13 + 33487757 = 33487770
37 + 33487733 = 33487770
53 + 33487717 = 33487770
89 + 33487681 = 33487770
131 + 33487639 = 33487770
139 + 33487631 = 33487770
149 + 33487621 = 33487770

Showing the first eight; more decompositions exist.
