Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154260, here are decompositions:

13 + 154247 = 154260
17 + 154243 = 154260
31 + 154229 = 154260
47 + 154213 = 154260
79 + 154181 = 154260
101 + 154159 = 154260
103 + 154157 = 154260
107 + 154153 = 154260

Showing the first eight; more decompositions exist.
