Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720876, here are decompositions:

37 + 8720839 = 8720876
67 + 8720809 = 8720876
79 + 8720797 = 8720876
103 + 8720773 = 8720876
163 + 8720713 = 8720876
379 + 8720497 = 8720876
397 + 8720479 = 8720876
487 + 8720389 = 8720876

Showing the first eight; more decompositions exist.
