Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154992, here are decompositions:

11 + 154981 = 154992
59 + 154933 = 154992
109 + 154883 = 154992
151 + 154841 = 154992
193 + 154799 = 154992
223 + 154769 = 154992
239 + 154753 = 154992
269 + 154723 = 154992

Showing the first eight; more decompositions exist.
