Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151320, here are decompositions:

17 + 151303 = 151320
31 + 151289 = 151320
41 + 151279 = 151320
47 + 151273 = 151320
67 + 151253 = 151320
73 + 151247 = 151320
79 + 151241 = 151320
83 + 151237 = 151320

Showing the first eight; more decompositions exist.
