Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131576, here are decompositions:

79 + 131497 = 131576
97 + 131479 = 131576
127 + 131449 = 131576
139 + 131437 = 131576
163 + 131413 = 131576
283 + 131293 = 131576
373 + 131203 = 131576
433 + 131143 = 131576

Showing the first eight; more decompositions exist.
