Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724184, here are decompositions:

  • 3 + 8724181 = 8724184
  • 23 + 8724161 = 8724184
  • 41 + 8724143 = 8724184
  • 83 + 8724101 = 8724184
  • 113 + 8724071 = 8724184
  • 191 + 8723993 = 8724184
  • 197 + 8723987 = 8724184
  • 233 + 8723951 = 8724184

Showing the first eight; more decompositions exist.
