Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732990, here are decompositions:

  • 67 + 8732923 = 8732990
  • 103 + 8732887 = 8732990
  • 151 + 8732839 = 8732990
  • 157 + 8732833 = 8732990
  • 193 + 8732797 = 8732990
  • 241 + 8732749 = 8732990
  • 271 + 8732719 = 8732990
  • 313 + 8732677 = 8732990

Showing the first eight; more decompositions exist.
