Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154650, here are decompositions:

7 + 154643 = 154650
29 + 154621 = 154650
31 + 154619 = 154650
37 + 154613 = 154650
59 + 154591 = 154650
61 + 154589 = 154650
71 + 154579 = 154650
79 + 154571 = 154650

Showing the first eight; more decompositions exist.
