Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645804, here are decompositions:

31 + 8645773 = 8645804
43 + 8645761 = 8645804
151 + 8645653 = 8645804
157 + 8645647 = 8645804
313 + 8645491 = 8645804
373 + 8645431 = 8645804
397 + 8645407 = 8645804
463 + 8645341 = 8645804

Showing the first eight; more decompositions exist.
