Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42940, here are decompositions:

  • 3 + 42937 = 42940
  • 11 + 42929 = 42940
  • 17 + 42923 = 42940
  • 41 + 42899 = 42940
  • 101 + 42839 = 42940
  • 167 + 42773 = 42940
  • 173 + 42767 = 42940
  • 197 + 42743 = 42940

Showing the first eight; more decompositions exist.
