Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87884, here are decompositions:

3 + 87881 = 87884
7 + 87877 = 87884
31 + 87853 = 87884
73 + 87811 = 87884
163 + 87721 = 87884
193 + 87691 = 87884
241 + 87643 = 87884
271 + 87613 = 87884

Showing the first eight; more decompositions exist.
