Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154530, here are decompositions:

7 + 154523 = 154530
29 + 154501 = 154530
37 + 154493 = 154530
43 + 154487 = 154530
71 + 154459 = 154530
107 + 154423 = 154530
113 + 154417 = 154530
157 + 154373 = 154530

Showing the first eight; more decompositions exist.
