Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636942, here are decompositions:

  • 19 + 8636923 = 8636942
  • 31 + 8636911 = 8636942
  • 43 + 8636899 = 8636942
  • 73 + 8636869 = 8636942
  • 103 + 8636839 = 8636942
  • 151 + 8636791 = 8636942
  • 163 + 8636779 = 8636942
  • 229 + 8636713 = 8636942

Showing the first eight; more decompositions exist.
