Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698280, here are decompositions:

67 + 8698213 = 8698280
127 + 8698153 = 8698280
271 + 8698009 = 8698280
307 + 8697973 = 8698280
313 + 8697967 = 8698280
337 + 8697943 = 8698280
379 + 8697901 = 8698280
421 + 8697859 = 8698280

Showing the first eight; more decompositions exist.
