Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701664, here are decompositions:

7 + 8701657 = 8701664
43 + 8701621 = 8701664
157 + 8701507 = 8701664
241 + 8701423 = 8701664
397 + 8701267 = 8701664
421 + 8701243 = 8701664
457 + 8701207 = 8701664
487 + 8701177 = 8701664

Showing the first eight; more decompositions exist.
