Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142470, here are decompositions:

17 + 142453 = 142470
37 + 142433 = 142470
43 + 142427 = 142470
67 + 142403 = 142470
79 + 142391 = 142470
89 + 142381 = 142470
101 + 142369 = 142470
113 + 142357 = 142470

Showing the first eight; more decompositions exist.
