Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87758, here are decompositions:

7 + 87751 = 87758
19 + 87739 = 87758
37 + 87721 = 87758
61 + 87697 = 87758
67 + 87691 = 87758
79 + 87679 = 87758
109 + 87649 = 87758
127 + 87631 = 87758

Showing the first eight; more decompositions exist.
