Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131496, here are decompositions:

7 + 131489 = 131496
17 + 131479 = 131496
19 + 131477 = 131496
47 + 131449 = 131496
59 + 131437 = 131496
83 + 131413 = 131496
139 + 131357 = 131496
179 + 131317 = 131496

Showing the first eight; more decompositions exist.
