Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131598, here are decompositions:

7 + 131591 = 131598
17 + 131581 = 131598
37 + 131561 = 131598
79 + 131519 = 131598
97 + 131501 = 131598
101 + 131497 = 131598
109 + 131489 = 131598
149 + 131449 = 131598

Showing the first eight; more decompositions exist.
