Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636478, here are decompositions:

  • 5 + 8636473 = 8636478
  • 29 + 8636449 = 8636478
  • 89 + 8636389 = 8636478
  • 101 + 8636377 = 8636478
  • 131 + 8636347 = 8636478
  • 239 + 8636239 = 8636478
  • 241 + 8636237 = 8636478
  • 311 + 8636167 = 8636478

Showing the first eight; more decompositions exist.
