Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87842, here are decompositions:

31 + 87811 = 87842
103 + 87739 = 87842
151 + 87691 = 87842
163 + 87679 = 87842
193 + 87649 = 87842
199 + 87643 = 87842
211 + 87631 = 87842
229 + 87613 = 87842

Showing the first eight; more decompositions exist.
