Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679280, here are decompositions:

  • 3 + 8679277 = 8679280
  • 59 + 8679221 = 8679280
  • 101 + 8679179 = 8679280
  • 317 + 8678963 = 8679280
  • 347 + 8678933 = 8679280
  • 353 + 8678927 = 8679280
  • 503 + 8678777 = 8679280
  • 521 + 8678759 = 8679280

Showing the first eight; more decompositions exist.
