Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87756, here are decompositions:

5 + 87751 = 87756
13 + 87743 = 87756
17 + 87739 = 87756
37 + 87719 = 87756
59 + 87697 = 87756
73 + 87683 = 87756
107 + 87649 = 87756
113 + 87643 = 87756

Showing the first eight; more decompositions exist.
