Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636972, here are decompositions:

  • 13 + 8636959 = 8636972
  • 61 + 8636911 = 8636972
  • 73 + 8636899 = 8636972
  • 79 + 8636893 = 8636972
  • 103 + 8636869 = 8636972
  • 181 + 8636791 = 8636972
  • 193 + 8636779 = 8636972
  • 271 + 8636701 = 8636972

Showing the first eight; more decompositions exist.
