Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11902, here are decompositions:

  • 5 + 11897 = 11902
  • 71 + 11831 = 11902
  • 89 + 11813 = 11902
  • 101 + 11801 = 11902
  • 113 + 11789 = 11902
  • 269 + 11633 = 11902
  • 281 + 11621 = 11902
  • 353 + 11549 = 11902

Showing the first eight; more decompositions exist.
