Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154686, here are decompositions:

5 + 154681 = 154686
17 + 154669 = 154686
19 + 154667 = 154686
43 + 154643 = 154686
67 + 154619 = 154686
73 + 154613 = 154686
97 + 154589 = 154686
107 + 154579 = 154686

Showing the first eight; more decompositions exist.
