Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739970, here are decompositions:

  • 3 + 8739967 = 8739970
  • 17 + 8739953 = 8739970
  • 53 + 8739917 = 8739970
  • 59 + 8739911 = 8739970
  • 101 + 8739869 = 8739970
  • 149 + 8739821 = 8739970
  • 167 + 8739803 = 8739970
  • 257 + 8739713 = 8739970

Showing the first eight; more decompositions exist.
