Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137574, here are decompositions:

7 + 137567 = 137574
37 + 137537 = 137574
67 + 137507 = 137574
83 + 137491 = 137574
97 + 137477 = 137574
127 + 137447 = 137574
131 + 137443 = 137574
137 + 137437 = 137574

Showing the first eight; more decompositions exist.
