Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618930, here are decompositions:

  • 7 + 8618923 = 8618930
  • 13 + 8618917 = 8618930
  • 37 + 8618893 = 8618930
  • 79 + 8618851 = 8618930
  • 97 + 8618833 = 8618930
  • 181 + 8618749 = 8618930
  • 193 + 8618737 = 8618930
  • 241 + 8618689 = 8618930

Showing the first eight; more decompositions exist.
