Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636404, here are decompositions:

17 + 8636387 = 8636404
167 + 8636237 = 8636404
263 + 8636141 = 8636404
281 + 8636123 = 8636404
311 + 8636093 = 8636404
317 + 8636087 = 8636404
347 + 8636057 = 8636404
383 + 8636021 = 8636404

Showing the first eight; more decompositions exist.
