Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154854, here are decompositions:

5 + 154849 = 154854
13 + 154841 = 154854
31 + 154823 = 154854
47 + 154807 = 154854
67 + 154787 = 154854
101 + 154753 = 154854
107 + 154747 = 154854
127 + 154727 = 154854

Showing the first eight; more decompositions exist.
