Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701868, here are decompositions:

79 + 8701789 = 8701868
127 + 8701741 = 8701868
139 + 8701729 = 8701868
211 + 8701657 = 8701868
337 + 8701531 = 8701868
349 + 8701519 = 8701868
379 + 8701489 = 8701868
421 + 8701447 = 8701868

Showing the first eight; more decompositions exist.
