Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88840, here are decompositions:

23 + 88817 = 88840
29 + 88811 = 88840
41 + 88799 = 88840
47 + 88793 = 88840
173 + 88667 = 88840
179 + 88661 = 88840
197 + 88643 = 88840
233 + 88607 = 88840

Showing the first eight; more decompositions exist.
