Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701658, here are decompositions:

37 + 8701621 = 8701658
127 + 8701531 = 8701658
139 + 8701519 = 8701658
151 + 8701507 = 8701658
181 + 8701477 = 8701658
211 + 8701447 = 8701658
337 + 8701321 = 8701658
349 + 8701309 = 8701658

Showing the first eight; more decompositions exist.
