Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669580, here are decompositions:

37 + 8669543 = 8669580
53 + 8669527 = 8669580
67 + 8669513 = 8669580
79 + 8669501 = 8669580
97 + 8669483 = 8669580
103 + 8669477 = 8669580
137 + 8669443 = 8669580
163 + 8669417 = 8669580

Showing the first eight; more decompositions exist.
