Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700090, here are decompositions:

  • 11 + 8700079 = 8700090
  • 19 + 8700071 = 8700090
  • 31 + 8700059 = 8700090
  • 43 + 8700047 = 8700090
  • 53 + 8700037 = 8700090
  • 59 + 8700031 = 8700090
  • 71 + 8700019 = 8700090
  • 79 + 8700011 = 8700090

Showing the first eight; more decompositions exist.
