Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002990, here are decompositions:

  • 11 + 1002979 = 1002990
  • 17 + 1002973 = 1002990
  • 59 + 1002931 = 1002990
  • 61 + 1002929 = 1002990
  • 73 + 1002917 = 1002990
  • 97 + 1002893 = 1002990
  • 103 + 1002887 = 1002990
  • 127 + 1002863 = 1002990

Showing the first eight; more decompositions exist.
