Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618980, here are decompositions:

47 + 8618933 = 8618980
101 + 8618879 = 8618980
113 + 8618867 = 8618980
191 + 8618789 = 8618980
197 + 8618783 = 8618980
233 + 8618747 = 8618980
281 + 8618699 = 8618980
389 + 8618591 = 8618980

Showing the first eight; more decompositions exist.
