Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154518, here are decompositions:

17 + 154501 = 154518
31 + 154487 = 154518
59 + 154459 = 154518
79 + 154439 = 154518
101 + 154417 = 154518
109 + 154409 = 154518
131 + 154387 = 154518
149 + 154369 = 154518

Showing the first eight; more decompositions exist.
