Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142154, here are decompositions:

3 + 142151 = 142154
31 + 142123 = 142154
43 + 142111 = 142154
97 + 142057 = 142154
163 + 141991 = 142154
193 + 141961 = 142154
223 + 141931 = 142154
283 + 141871 = 142154

Showing the first eight; more decompositions exist.
