Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154806, here are decompositions:

7 + 154799 = 154806
17 + 154789 = 154806
19 + 154787 = 154806
37 + 154769 = 154806
53 + 154753 = 154806
59 + 154747 = 154806
73 + 154733 = 154806
79 + 154727 = 154806

Showing the first eight; more decompositions exist.
