Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487372, here are decompositions:

29 + 33487343 = 33487372
53 + 33487319 = 33487372
59 + 33487313 = 33487372
71 + 33487301 = 33487372
101 + 33487271 = 33487372
179 + 33487193 = 33487372
251 + 33487121 = 33487372
311 + 33487061 = 33487372

Showing the first eight; more decompositions exist.
