Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724884, here are decompositions:

13 + 8724871 = 8724884
37 + 8724847 = 8724884
97 + 8724787 = 8724884
163 + 8724721 = 8724884
241 + 8724643 = 8724884
283 + 8724601 = 8724884
373 + 8724511 = 8724884
397 + 8724487 = 8724884

Showing the first eight; more decompositions exist.
