Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680870, here are decompositions:

  • 47 + 8680823 = 8680870
  • 59 + 8680811 = 8680870
  • 89 + 8680781 = 8680870
  • 101 + 8680769 = 8680870
  • 137 + 8680733 = 8680870
  • 173 + 8680697 = 8680870
  • 179 + 8680691 = 8680870
  • 239 + 8680631 = 8680870

Showing the first eight; more decompositions exist.
