Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709442, here are decompositions:

11 + 8709431 = 8709442
59 + 8709383 = 8709442
251 + 8709191 = 8709442
293 + 8709149 = 8709442
383 + 8709059 = 8709442
479 + 8708963 = 8709442
593 + 8708849 = 8709442
701 + 8708741 = 8709442

Showing the first eight; more decompositions exist.
