Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72992, here are decompositions:

  • 19 + 72973 = 72992
  • 43 + 72949 = 72992
  • 61 + 72931 = 72992
  • 103 + 72889 = 72992
  • 109 + 72883 = 72992
  • 229 + 72763 = 72992
  • 313 + 72679 = 72992
  • 331 + 72661 = 72992

Showing the first eight; more decompositions exist.
