Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542942, here are decompositions:

  • 3 + 542939 = 542942
  • 19 + 542923 = 542942
  • 31 + 542911 = 542942
  • 151 + 542791 = 542942
  • 181 + 542761 = 542942
  • 223 + 542719 = 542942
  • 229 + 542713 = 542942
  • 409 + 542533 = 542942

Showing the first eight; more decompositions exist.
