Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709242, here are decompositions:

13 + 8709229 = 8709242
103 + 8709139 = 8709242
109 + 8709133 = 8709242
163 + 8709079 = 8709242
271 + 8708971 = 8709242
331 + 8708911 = 8709242
349 + 8708893 = 8709242
439 + 8708803 = 8709242

Showing the first eight; more decompositions exist.
