Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649004, here are decompositions:

3 + 8649001 = 8649004
83 + 8648921 = 8649004
137 + 8648867 = 8649004
167 + 8648837 = 8649004
173 + 8648831 = 8649004
191 + 8648813 = 8649004
257 + 8648747 = 8649004
263 + 8648741 = 8649004

Showing the first eight; more decompositions exist.
