Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154850, here are decompositions:

43 + 154807 = 154850
61 + 154789 = 154850
97 + 154753 = 154850
103 + 154747 = 154850
127 + 154723 = 154850
151 + 154699 = 154850
181 + 154669 = 154850
229 + 154621 = 154850

Showing the first eight; more decompositions exist.
