Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131604, here are decompositions:

13 + 131591 = 131604
23 + 131581 = 131604
43 + 131561 = 131604
61 + 131543 = 131604
97 + 131507 = 131604
103 + 131501 = 131604
107 + 131497 = 131604
127 + 131477 = 131604

Showing the first eight; more decompositions exist.
