Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648564, here are decompositions:

  • 7 + 8648557 = 8648564
  • 13 + 8648551 = 8648564
  • 31 + 8648533 = 8648564
  • 151 + 8648413 = 8648564
  • 193 + 8648371 = 8648564
  • 241 + 8648323 = 8648564
  • 313 + 8648251 = 8648564
  • 373 + 8648191 = 8648564

Showing the first eight; more decompositions exist.
