Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700238, here are decompositions:

167 + 8700071 = 8700238
179 + 8700059 = 8700238
191 + 8700047 = 8700238
227 + 8700011 = 8700238
257 + 8699981 = 8700238
269 + 8699969 = 8700238
359 + 8699879 = 8700238
431 + 8699807 = 8700238

Showing the first eight; more decompositions exist.
