Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8704688, here are decompositions:

37 + 8704651 = 8704688
67 + 8704621 = 8704688
79 + 8704609 = 8704688
271 + 8704417 = 8704688
337 + 8704351 = 8704688
379 + 8704309 = 8704688
409 + 8704279 = 8704688
571 + 8704117 = 8704688

Showing the first eight; more decompositions exist.
