Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691008, here are decompositions:

37 + 8690971 = 8691008
61 + 8690947 = 8691008
181 + 8690827 = 8691008
211 + 8690797 = 8691008
241 + 8690767 = 8691008
331 + 8690677 = 8691008
349 + 8690659 = 8691008
397 + 8690611 = 8691008

Showing the first eight; more decompositions exist.
