Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154340, here are decompositions:

7 + 154333 = 154340
19 + 154321 = 154340
37 + 154303 = 154340
61 + 154279 = 154340
73 + 154267 = 154340
97 + 154243 = 154340
127 + 154213 = 154340
157 + 154183 = 154340

Showing the first eight; more decompositions exist.
