Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137670, here are decompositions:

11 + 137659 = 137670
17 + 137653 = 137670
31 + 137639 = 137670
37 + 137633 = 137670
47 + 137623 = 137670
73 + 137597 = 137670
83 + 137587 = 137670
97 + 137573 = 137670

Showing the first eight; more decompositions exist.
