Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699980, here are decompositions:

  • 11 + 8699969 = 8699980
  • 101 + 8699879 = 8699980
  • 167 + 8699813 = 8699980
  • 173 + 8699807 = 8699980
  • 227 + 8699753 = 8699980
  • 257 + 8699723 = 8699980
  • 347 + 8699633 = 8699980
  • 461 + 8699519 = 8699980

Showing the first eight; more decompositions exist.
