Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726180, here are decompositions:

  • 37 + 8726143 = 8726180
  • 79 + 8726101 = 8726180
  • 163 + 8726017 = 8726180
  • 181 + 8725999 = 8726180
  • 193 + 8725987 = 8726180
  • 349 + 8725831 = 8726180
  • 367 + 8725813 = 8726180
  • 499 + 8725681 = 8726180

Showing the first eight; more decompositions exist.
