Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742622, here are decompositions:

71 + 8742551 = 8742622
173 + 8742449 = 8742622
263 + 8742359 = 8742622
269 + 8742353 = 8742622
359 + 8742263 = 8742622
461 + 8742161 = 8742622
563 + 8742059 = 8742622
761 + 8741861 = 8742622

Showing the first eight; more decompositions exist.
