Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759642, here are decompositions:

61 + 8759581 = 8759642
139 + 8759503 = 8759642
223 + 8759419 = 8759642
271 + 8759371 = 8759642
421 + 8759221 = 8759642
691 + 8758951 = 8759642
709 + 8758933 = 8759642
739 + 8758903 = 8759642

Showing the first eight; more decompositions exist.
