Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87814, here are decompositions:

3 + 87811 = 87814
11 + 87803 = 87814
17 + 87797 = 87814
47 + 87767 = 87814
71 + 87743 = 87814
113 + 87701 = 87814
131 + 87683 = 87814
173 + 87641 = 87814

Showing the first eight; more decompositions exist.
