Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700280, here are decompositions:

23 + 8700257 = 8700280
41 + 8700239 = 8700280
167 + 8700113 = 8700280
233 + 8700047 = 8700280
269 + 8700011 = 8700280
311 + 8699969 = 8700280
401 + 8699879 = 8700280
467 + 8699813 = 8700280

Showing the first eight; more decompositions exist.
