Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708438, here are decompositions:

  • 241 + 8708197 = 8708438
  • 337 + 8708101 = 8708438
  • 367 + 8708071 = 8708438
  • 421 + 8708017 = 8708438
  • 439 + 8707999 = 8708438
  • 499 + 8707939 = 8708438
  • 577 + 8707861 = 8708438
  • 601 + 8707837 = 8708438

Showing the first eight; more decompositions exist.
