Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487864, here are decompositions:

5 + 33487859 = 33487864
17 + 33487847 = 33487864
107 + 33487757 = 33487864
131 + 33487733 = 33487864
233 + 33487631 = 33487864
257 + 33487607 = 33487864
353 + 33487511 = 33487864
521 + 33487343 = 33487864

Showing the first eight; more decompositions exist.
