Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487750, here are decompositions:

17 + 33487733 = 33487750
239 + 33487511 = 33487750
431 + 33487319 = 33487750
449 + 33487301 = 33487750
479 + 33487271 = 33487750
503 + 33487247 = 33487750
557 + 33487193 = 33487750
563 + 33487187 = 33487750

Showing the first eight; more decompositions exist.
