Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720996, here are decompositions:

19 + 8720977 = 8720996
43 + 8720953 = 8720996
157 + 8720839 = 8720996
199 + 8720797 = 8720996
223 + 8720773 = 8720996
283 + 8720713 = 8720996
307 + 8720689 = 8720996
367 + 8720629 = 8720996

Showing the first eight; more decompositions exist.
