Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87956, here are decompositions:

13 + 87943 = 87956
79 + 87877 = 87956
103 + 87853 = 87956
163 + 87793 = 87956
277 + 87679 = 87956
307 + 87649 = 87956
313 + 87643 = 87956
367 + 87589 = 87956

Showing the first eight; more decompositions exist.
