Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137226, here are decompositions:

7 + 137219 = 137226
17 + 137209 = 137226
29 + 137197 = 137226
43 + 137183 = 137226
73 + 137153 = 137226
79 + 137147 = 137226
83 + 137143 = 137226
107 + 137119 = 137226

Showing the first eight; more decompositions exist.
