Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154758, here are decompositions:

5 + 154753 = 154758
11 + 154747 = 154758
31 + 154727 = 154758
59 + 154699 = 154758
67 + 154691 = 154758
89 + 154669 = 154758
137 + 154621 = 154758
139 + 154619 = 154758

Showing the first eight; more decompositions exist.
