Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182224, here are decompositions:

23 + 182201 = 182224
47 + 182177 = 182224
83 + 182141 = 182224
101 + 182123 = 182224
113 + 182111 = 182224
167 + 182057 = 182224
197 + 182027 = 182224
227 + 181997 = 182224

Showing the first eight; more decompositions exist.
