Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137658, here are decompositions:

5 + 137653 = 137658
19 + 137639 = 137658
61 + 137597 = 137658
71 + 137587 = 137658
139 + 137519 = 137658
151 + 137507 = 137658
167 + 137491 = 137658
181 + 137477 = 137658

Showing the first eight; more decompositions exist.
