Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690100, here are decompositions:

7 + 8690093 = 8690100
11 + 8690089 = 8690100
31 + 8690069 = 8690100
37 + 8690063 = 8690100
59 + 8690041 = 8690100
103 + 8689997 = 8690100
113 + 8689987 = 8690100
131 + 8689969 = 8690100

Showing the first eight; more decompositions exist.
