Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642804, here are decompositions:

31 + 8642773 = 8642804
43 + 8642761 = 8642804
223 + 8642581 = 8642804
271 + 8642533 = 8642804
337 + 8642467 = 8642804
421 + 8642383 = 8642804
523 + 8642281 = 8642804
607 + 8642197 = 8642804

Showing the first eight; more decompositions exist.
