Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 902, here are decompositions:

  • 19 + 883 = 902
  • 43 + 859 = 902
  • 73 + 829 = 902
  • 79 + 823 = 902
  • 151 + 751 = 902
  • 163 + 739 = 902
  • 193 + 709 = 902
  • 211 + 691 = 902

Showing the first eight; more decompositions exist.
