Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690028, here are decompositions:

31 + 8689997 = 8690028
41 + 8689987 = 8690028
47 + 8689981 = 8690028
59 + 8689969 = 8690028
71 + 8689957 = 8690028
79 + 8689949 = 8690028
211 + 8689817 = 8690028
229 + 8689799 = 8690028

Showing the first eight; more decompositions exist.
