Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648918, here are decompositions:

37 + 8648881 = 8648918
79 + 8648839 = 8648918
127 + 8648791 = 8648918
139 + 8648779 = 8648918
181 + 8648737 = 8648918
241 + 8648677 = 8648918
367 + 8648551 = 8648918
547 + 8648371 = 8648918

Showing the first eight; more decompositions exist.
