Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709808, here are decompositions:

71 + 8709737 = 8709808
89 + 8709719 = 8709808
131 + 8709677 = 8709808
197 + 8709611 = 8709808
281 + 8709527 = 8709808
347 + 8709461 = 8709808
431 + 8709377 = 8709808
491 + 8709317 = 8709808

Showing the first eight; more decompositions exist.
