Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152280, here are decompositions:

13 + 152267 = 152280
31 + 152249 = 152280
41 + 152239 = 152280
61 + 152219 = 152280
67 + 152213 = 152280
83 + 152197 = 152280
97 + 152183 = 152280
157 + 152123 = 152280

Showing the first eight; more decompositions exist.
