Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731898, here are decompositions:

  • 31 + 8731867 = 8731898
  • 37 + 8731861 = 8731898
  • 67 + 8731831 = 8731898
  • 79 + 8731819 = 8731898
  • 199 + 8731699 = 8731898
  • 211 + 8731687 = 8731898
  • 271 + 8731627 = 8731898
  • 367 + 8731531 = 8731898

Showing the first eight; more decompositions exist.
