Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10902, here are decompositions:

  • 11 + 10891 = 10902
  • 13 + 10889 = 10902
  • 19 + 10883 = 10902
  • 41 + 10861 = 10902
  • 43 + 10859 = 10902
  • 71 + 10831 = 10902
  • 103 + 10799 = 10902
  • 113 + 10789 = 10902

Showing the first eight; more decompositions exist.
