Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154428, here are decompositions:

5 + 154423 = 154428
11 + 154417 = 154428
19 + 154409 = 154428
41 + 154387 = 154428
59 + 154369 = 154428
89 + 154339 = 154428
107 + 154321 = 154428
137 + 154291 = 154428

Showing the first eight; more decompositions exist.
