Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726990, here are decompositions:

  • 3 + 8726987 = 8726990
  • 7 + 8726983 = 8726990
  • 37 + 8726953 = 8726990
  • 67 + 8726923 = 8726990
  • 73 + 8726917 = 8726990
  • 127 + 8726863 = 8726990
  • 229 + 8726761 = 8726990
  • 277 + 8726713 = 8726990

Showing the first eight; more decompositions exist.
