Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701328, here are decompositions:

7 + 8701321 = 8701328
19 + 8701309 = 8701328
61 + 8701267 = 8701328
151 + 8701177 = 8701328
211 + 8701117 = 8701328
271 + 8701057 = 8701328
397 + 8700931 = 8701328
457 + 8700871 = 8701328

Showing the first eight; more decompositions exist.
