Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42988, here are decompositions:

  • 59 + 42929 = 42988
  • 89 + 42899 = 42988
  • 149 + 42839 = 42988
  • 167 + 42821 = 42988
  • 191 + 42797 = 42988
  • 251 + 42737 = 42988
  • 269 + 42719 = 42988
  • 311 + 42677 = 42988

Showing the first eight; more decompositions exist.
