Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619622, here are decompositions:

29 + 8619593 = 8619622
71 + 8619551 = 8619622
83 + 8619539 = 8619622
113 + 8619509 = 8619622
131 + 8619491 = 8619622
149 + 8619473 = 8619622
191 + 8619431 = 8619622
269 + 8619353 = 8619622

Showing the first eight; more decompositions exist.
