Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631004, here are decompositions:

3 + 8631001 = 8631004
101 + 8630903 = 8631004
167 + 8630837 = 8631004
191 + 8630813 = 8631004
233 + 8630771 = 8631004
521 + 8630483 = 8631004
587 + 8630417 = 8631004
617 + 8630387 = 8631004

Showing the first eight; more decompositions exist.
