Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137650, here are decompositions:

11 + 137639 = 137650
17 + 137633 = 137650
53 + 137597 = 137650
83 + 137567 = 137650
113 + 137537 = 137650
131 + 137519 = 137650
167 + 137483 = 137650
173 + 137477 = 137650

Showing the first eight; more decompositions exist.
