Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691080, here are decompositions:

37 + 8691043 = 8691080
61 + 8691019 = 8691080
109 + 8690971 = 8691080
127 + 8690953 = 8691080
163 + 8690917 = 8691080
283 + 8690797 = 8691080
313 + 8690767 = 8691080
367 + 8690713 = 8691080

Showing the first eight; more decompositions exist.
