Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154506, here are decompositions:

5 + 154501 = 154506
13 + 154493 = 154506
19 + 154487 = 154506
47 + 154459 = 154506
67 + 154439 = 154506
83 + 154423 = 154506
89 + 154417 = 154506
97 + 154409 = 154506

Showing the first eight; more decompositions exist.
