Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700988, here are decompositions:

41 + 8700947 = 8700988
47 + 8700941 = 8700988
389 + 8700599 = 8700988
449 + 8700539 = 8700988
467 + 8700521 = 8700988
521 + 8700467 = 8700988
557 + 8700431 = 8700988
587 + 8700401 = 8700988

Showing the first eight; more decompositions exist.
