Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648404, here are decompositions:

71 + 8648333 = 8648404
137 + 8648267 = 8648404
293 + 8648111 = 8648404
311 + 8648093 = 8648404
467 + 8647937 = 8648404
491 + 8647913 = 8648404
587 + 8647817 = 8648404
1013 + 8647391 = 8648404

Showing the first eight; more decompositions exist.
