Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487830, here are decompositions:

11 + 33487819 = 33487830
17 + 33487813 = 33487830
59 + 33487771 = 33487830
71 + 33487759 = 33487830
73 + 33487757 = 33487830
97 + 33487733 = 33487830
113 + 33487717 = 33487830
149 + 33487681 = 33487830

Showing the first eight; more decompositions exist.
