Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542990, here are decompositions:

  • 3 + 542987 = 542990
  • 43 + 542947 = 542990
  • 67 + 542923 = 542990
  • 79 + 542911 = 542990
  • 193 + 542797 = 542990
  • 199 + 542791 = 542990
  • 229 + 542761 = 542990
  • 271 + 542719 = 542990

Showing the first eight; more decompositions exist.
