Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709818, here are decompositions:

37 + 8709781 = 8709818
67 + 8709751 = 8709818
97 + 8709721 = 8709818
349 + 8709469 = 8709818
457 + 8709361 = 8709818
547 + 8709271 = 8709818
631 + 8709187 = 8709818
739 + 8709079 = 8709818

Showing the first eight; more decompositions exist.
