Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720088, here are decompositions:

  • 7 + 8720081 = 8720088
  • 17 + 8720071 = 8720088
  • 31 + 8720057 = 8720088
  • 61 + 8720027 = 8720088
  • 89 + 8719999 = 8720088
  • 101 + 8719987 = 8720088
  • 127 + 8719961 = 8720088
  • 137 + 8719951 = 8720088

Showing the first eight; more decompositions exist.
