Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701240, here are decompositions:

29 + 8701211 = 8701240
47 + 8701193 = 8701240
173 + 8701067 = 8701240
227 + 8701013 = 8701240
239 + 8701001 = 8701240
293 + 8700947 = 8701240
347 + 8700893 = 8701240
467 + 8700773 = 8701240

Showing the first eight; more decompositions exist.
