Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658404, here are decompositions:

127 + 8658277 = 8658404
211 + 8658193 = 8658404
421 + 8657983 = 8658404
523 + 8657881 = 8658404
571 + 8657833 = 8658404
577 + 8657827 = 8658404
673 + 8657731 = 8658404
1471 + 8656933 = 8658404

Showing the first eight; more decompositions exist.
