Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724888, here are decompositions:

5 + 8724883 = 8724888
17 + 8724871 = 8724888
41 + 8724847 = 8724888
61 + 8724827 = 8724888
89 + 8724799 = 8724888
101 + 8724787 = 8724888
149 + 8724739 = 8724888
167 + 8724721 = 8724888

Showing the first eight; more decompositions exist.
