Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612210, here are decompositions:

  • 43 + 8612167 = 8612210
  • 151 + 8612059 = 8612210
  • 199 + 8612011 = 8612210
  • 223 + 8611987 = 8612210
  • 241 + 8611969 = 8612210
  • 307 + 8611903 = 8612210
  • 331 + 8611879 = 8612210
  • 337 + 8611873 = 8612210

Showing the first eight; more decompositions exist.
