Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42012, here are decompositions:

  • 13 + 41999 = 42012
  • 29 + 41983 = 42012
  • 31 + 41981 = 42012
  • 43 + 41969 = 42012
  • 53 + 41959 = 42012
  • 59 + 41953 = 42012
  • 71 + 41941 = 42012
  • 101 + 41911 = 42012

Showing the first eight; more decompositions exist.
