Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611970, here are decompositions:

  • 67 + 8611903 = 8611970
  • 79 + 8611891 = 8611970
  • 97 + 8611873 = 8611970
  • 151 + 8611819 = 8611970
  • 181 + 8611789 = 8611970
  • 307 + 8611663 = 8611970
  • 337 + 8611633 = 8611970
  • 373 + 8611597 = 8611970

Showing the first eight; more decompositions exist.
