Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604440, here are decompositions:

37 + 8604403 = 8604440
67 + 8604373 = 8604440
181 + 8604259 = 8604440
199 + 8604241 = 8604440
283 + 8604157 = 8604440
373 + 8604067 = 8604440
487 + 8603953 = 8604440
547 + 8603893 = 8604440

Showing the first eight; more decompositions exist.
