Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742080, here are decompositions:

  • 3 + 8742077 = 8742080
  • 13 + 8742067 = 8742080
  • 43 + 8742037 = 8742080
  • 97 + 8741983 = 8742080
  • 103 + 8741977 = 8742080
  • 157 + 8741923 = 8742080
  • 241 + 8741839 = 8742080
  • 283 + 8741797 = 8742080

Showing the first eight; more decompositions exist.
