Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641804, here are decompositions:

23 + 8641781 = 8641804
71 + 8641733 = 8641804
107 + 8641697 = 8641804
131 + 8641673 = 8641804
173 + 8641631 = 8641804
191 + 8641613 = 8641804
233 + 8641571 = 8641804
257 + 8641547 = 8641804

Showing the first eight; more decompositions exist.
