Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701628, here are decompositions:

7 + 8701621 = 8701628
97 + 8701531 = 8701628
109 + 8701519 = 8701628
139 + 8701489 = 8701628
151 + 8701477 = 8701628
181 + 8701447 = 8701628
307 + 8701321 = 8701628
349 + 8701279 = 8701628

Showing the first eight; more decompositions exist.
