Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131502, here are decompositions:

5 + 131497 = 131502
13 + 131489 = 131502
23 + 131479 = 131502
53 + 131449 = 131502
61 + 131441 = 131502
71 + 131431 = 131502
89 + 131413 = 131502
131 + 131371 = 131502

Showing the first eight; more decompositions exist.
