Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701490, here are decompositions:

13 + 8701477 = 8701490
43 + 8701447 = 8701490
67 + 8701423 = 8701490
181 + 8701309 = 8701490
211 + 8701279 = 8701490
223 + 8701267 = 8701490
283 + 8701207 = 8701490
313 + 8701177 = 8701490

Showing the first eight; more decompositions exist.
