Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154730, here are decompositions:

3 + 154727 = 154730
7 + 154723 = 154730
31 + 154699 = 154730
61 + 154669 = 154730
109 + 154621 = 154730
139 + 154591 = 154730
151 + 154579 = 154730
157 + 154573 = 154730

Showing the first eight; more decompositions exist.
