Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157146, here are decompositions:

5 + 157141 = 157146
13 + 157133 = 157146
19 + 157127 = 157146
37 + 157109 = 157146
43 + 157103 = 157146
89 + 157057 = 157146
97 + 157049 = 157146
109 + 157037 = 157146

Showing the first eight; more decompositions exist.
