Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87800, here are decompositions:

3 + 87797 = 87800
7 + 87793 = 87800
61 + 87739 = 87800
79 + 87721 = 87800
103 + 87697 = 87800
109 + 87691 = 87800
151 + 87649 = 87800
157 + 87643 = 87800

Showing the first eight; more decompositions exist.
