Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646830, here are decompositions:

  • 7 + 8646823 = 8646830
  • 13 + 8646817 = 8646830
  • 37 + 8646793 = 8646830
  • 79 + 8646751 = 8646830
  • 109 + 8646721 = 8646830
  • 163 + 8646667 = 8646830
  • 223 + 8646607 = 8646830
  • 271 + 8646559 = 8646830

Showing the first eight; more decompositions exist.
