Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154440, here are decompositions:

17 + 154423 = 154440
23 + 154417 = 154440
31 + 154409 = 154440
53 + 154387 = 154440
67 + 154373 = 154440
71 + 154369 = 154440
89 + 154351 = 154440
101 + 154339 = 154440

Showing the first eight; more decompositions exist.
