Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154320, here are decompositions:

7 + 154313 = 154320
17 + 154303 = 154320
29 + 154291 = 154320
41 + 154279 = 154320
43 + 154277 = 154320
53 + 154267 = 154320
73 + 154247 = 154320
107 + 154213 = 154320

Showing the first eight; more decompositions exist.
