Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131448, here are decompositions:

7 + 131441 = 131448
11 + 131437 = 131448
17 + 131431 = 131448
67 + 131381 = 131448
127 + 131321 = 131448
131 + 131317 = 131448
137 + 131311 = 131448
151 + 131297 = 131448

Showing the first eight; more decompositions exist.
