Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156146, here are decompositions:

7 + 156139 = 156146
19 + 156127 = 156146
37 + 156109 = 156146
127 + 156019 = 156146
139 + 156007 = 156146
283 + 155863 = 156146
313 + 155833 = 156146
337 + 155809 = 156146

Showing the first eight; more decompositions exist.
