Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661028, here are decompositions:

41 + 8660987 = 8661028
59 + 8660969 = 8661028
107 + 8660921 = 8661028
137 + 8660891 = 8661028
281 + 8660747 = 8661028
347 + 8660681 = 8661028
419 + 8660609 = 8661028
449 + 8660579 = 8661028

Showing the first eight; more decompositions exist.
