Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622742, here are decompositions:

59 + 8622683 = 8622742
131 + 8622611 = 8622742
179 + 8622563 = 8622742
251 + 8622491 = 8622742
269 + 8622473 = 8622742
281 + 8622461 = 8622742
383 + 8622359 = 8622742
389 + 8622353 = 8622742

Showing the first eight; more decompositions exist.
