Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705858, here are decompositions:

  • 67 + 8705791 = 8705858
  • 241 + 8705617 = 8705858
  • 307 + 8705551 = 8705858
  • 331 + 8705527 = 8705858
  • 367 + 8705491 = 8705858
  • 397 + 8705461 = 8705858
  • 409 + 8705449 = 8705858
  • 439 + 8705419 = 8705858

Showing the first eight; more decompositions exist.
