Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90872, here are decompositions:

  • 31 + 90841 = 90872
  • 79 + 90793 = 90872
  • 163 + 90709 = 90872
  • 193 + 90679 = 90872
  • 241 + 90631 = 90872
  • 349 + 90523 = 90872
  • 373 + 90499 = 90872
  • 433 + 90439 = 90872

Showing the first eight; more decompositions exist.
