Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637874, here are decompositions:

  • 5 + 8637869 = 8637874
  • 53 + 8637821 = 8637874
  • 83 + 8637791 = 8637874
  • 173 + 8637701 = 8637874
  • 233 + 8637641 = 8637874
  • 257 + 8637617 = 8637874
  • 263 + 8637611 = 8637874
  • 347 + 8637527 = 8637874

Showing the first eight; more decompositions exist.
