Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701388, here are decompositions:

67 + 8701321 = 8701388
79 + 8701309 = 8701388
109 + 8701279 = 8701388
181 + 8701207 = 8701388
211 + 8701177 = 8701388
271 + 8701117 = 8701388
307 + 8701081 = 8701388
331 + 8701057 = 8701388

Showing the first eight; more decompositions exist.
