Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991352, here are decompositions:

  • 79 + 991273 = 991352
  • 151 + 991201 = 991352
  • 181 + 991171 = 991352
  • 223 + 991129 = 991352
  • 283 + 991069 = 991352
  • 379 + 990973 = 991352
  • 463 + 990889 = 991352
  • 619 + 990733 = 991352

Showing the first eight; more decompositions exist.
