Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33472390, here are decompositions:

59 + 33472331 = 33472390
89 + 33472301 = 33472390
167 + 33472223 = 33472390
173 + 33472217 = 33472390
197 + 33472193 = 33472390
227 + 33472163 = 33472390
251 + 33472139 = 33472390
311 + 33472079 = 33472390

Showing the first eight; more decompositions exist.
