Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709122, here are decompositions:

43 + 8709079 = 8709122
151 + 8708971 = 8709122
211 + 8708911 = 8709122
229 + 8708893 = 8709122
421 + 8708701 = 8709122
601 + 8708521 = 8709122
613 + 8708509 = 8709122
661 + 8708461 = 8709122

Showing the first eight; more decompositions exist.
