Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691248, here are decompositions:

19 + 8691229 = 8691248
37 + 8691211 = 8691248
61 + 8691187 = 8691248
157 + 8691091 = 8691248
229 + 8691019 = 8691248
277 + 8690971 = 8691248
331 + 8690917 = 8691248
421 + 8690827 = 8691248

Showing the first eight; more decompositions exist.
