Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618078, here are decompositions:

  • 19 + 8618059 = 8618078
  • 31 + 8618047 = 8618078
  • 37 + 8618041 = 8618078
  • 151 + 8617927 = 8618078
  • 241 + 8617837 = 8618078
  • 379 + 8617699 = 8618078
  • 397 + 8617681 = 8618078
  • 631 + 8617447 = 8618078

Showing the first eight; more decompositions exist.
