Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181264, here are decompositions:

11 + 181253 = 181264
53 + 181211 = 181264
71 + 181193 = 181264
107 + 181157 = 181264
233 + 181031 = 181264
263 + 181001 = 181264
467 + 180797 = 181264
491 + 180773 = 181264

Showing the first eight; more decompositions exist.
