Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648980, here are decompositions:

59 + 8648921 = 8648980
101 + 8648879 = 8648980
113 + 8648867 = 8648980
149 + 8648831 = 8648980
167 + 8648813 = 8648980
233 + 8648747 = 8648980
239 + 8648741 = 8648980
251 + 8648729 = 8648980

Showing the first eight; more decompositions exist.
