Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151224, here are decompositions:

11 + 151213 = 151224
23 + 151201 = 151224
53 + 151171 = 151224
61 + 151163 = 151224
67 + 151157 = 151224
71 + 151153 = 151224
83 + 151141 = 151224
103 + 151121 = 151224

Showing the first eight; more decompositions exist.
