Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487186, here are decompositions:

23 + 33487163 = 33487186
137 + 33487049 = 33487186
233 + 33486953 = 33487186
269 + 33486917 = 33487186
353 + 33486833 = 33487186
419 + 33486767 = 33487186
563 + 33486623 = 33487186
599 + 33486587 = 33487186

Showing the first eight; more decompositions exist.
