Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611024, here are decompositions:

  • 7 + 31611017 = 31611024
  • 13 + 31611011 = 31611024
  • 113 + 31610911 = 31611024
  • 131 + 31610893 = 31611024
  • 157 + 31610867 = 31611024
  • 233 + 31610791 = 31611024
  • 251 + 31610773 = 31611024
  • 283 + 31610741 = 31611024

Showing the first eight; more decompositions exist.
