Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487432, here are decompositions:

89 + 33487343 = 33487432
113 + 33487319 = 33487432
131 + 33487301 = 33487432
239 + 33487193 = 33487432
269 + 33487163 = 33487432
281 + 33487151 = 33487432
311 + 33487121 = 33487432
383 + 33487049 = 33487432

Showing the first eight; more decompositions exist.
