Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636838, here are decompositions:

  • 19 + 8636819 = 8636838
  • 37 + 8636801 = 8636838
  • 47 + 8636791 = 8636838
  • 59 + 8636779 = 8636838
  • 79 + 8636759 = 8636838
  • 97 + 8636741 = 8636838
  • 101 + 8636737 = 8636838
  • 137 + 8636701 = 8636838

Showing the first eight; more decompositions exist.
