Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687974, here are decompositions:

11 + 8687963 = 8687974
83 + 8687891 = 8687974
101 + 8687873 = 8687974
461 + 8687513 = 8687974
521 + 8687453 = 8687974
587 + 8687387 = 8687974
593 + 8687381 = 8687974
653 + 8687321 = 8687974

Showing the first eight; more decompositions exist.
