Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701988, here are decompositions:

37 + 8701951 = 8701988
67 + 8701921 = 8701988
199 + 8701789 = 8701988
241 + 8701747 = 8701988
331 + 8701657 = 8701988
367 + 8701621 = 8701988
457 + 8701531 = 8701988
499 + 8701489 = 8701988

Showing the first eight; more decompositions exist.
