Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137604, here are decompositions:

7 + 137597 = 137604
11 + 137593 = 137604
17 + 137587 = 137604
31 + 137573 = 137604
37 + 137567 = 137604
67 + 137537 = 137604
97 + 137507 = 137604
113 + 137491 = 137604

Showing the first eight; more decompositions exist.
