Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137244, here are decompositions:

5 + 137239 = 137244
43 + 137201 = 137244
47 + 137197 = 137244
53 + 137191 = 137244
61 + 137183 = 137244
67 + 137177 = 137244
97 + 137147 = 137244
101 + 137143 = 137244

Showing the first eight; more decompositions exist.
