Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143460, here are decompositions:

17 + 143443 = 143460
41 + 143419 = 143460
47 + 143413 = 143460
59 + 143401 = 143460
73 + 143387 = 143460
103 + 143357 = 143460
127 + 143333 = 143460
131 + 143329 = 143460

Showing the first eight; more decompositions exist.
