Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541638, here are decompositions:

  • 7 + 541631 = 541638
  • 59 + 541579 = 541638
  • 61 + 541577 = 541638
  • 67 + 541571 = 541638
  • 89 + 541549 = 541638
  • 101 + 541537 = 541638
  • 107 + 541531 = 541638
  • 109 + 541529 = 541638

Showing the first eight; more decompositions exist.
