Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481390, here are decompositions:

23 + 33481367 = 33481390
29 + 33481361 = 33481390
101 + 33481289 = 33481390
197 + 33481193 = 33481390
227 + 33481163 = 33481390
317 + 33481073 = 33481390
353 + 33481037 = 33481390
419 + 33480971 = 33481390

Showing the first eight; more decompositions exist.
