Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700188, here are decompositions:

  • 19 + 8700169 = 8700188
  • 67 + 8700121 = 8700188
  • 109 + 8700079 = 8700188
  • 151 + 8700037 = 8700188
  • 157 + 8700031 = 8700188
  • 181 + 8700007 = 8700188
  • 229 + 8699959 = 8700188
  • 241 + 8699947 = 8700188

Showing the first eight; more decompositions exist.
