Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133240, here are decompositions:

53 + 133187 = 133240
71 + 133169 = 133240
83 + 133157 = 133240
131 + 133109 = 133240
137 + 133103 = 133240
167 + 133073 = 133240
227 + 133013 = 133240
251 + 132989 = 133240

Showing the first eight; more decompositions exist.
