Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137286, here are decompositions:

7 + 137279 = 137286
13 + 137273 = 137286
47 + 137239 = 137286
67 + 137219 = 137286
89 + 137197 = 137286
103 + 137183 = 137286
109 + 137177 = 137286
139 + 137147 = 137286

Showing the first eight; more decompositions exist.
