Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611152, here are decompositions:

  • 103 + 31611049 = 31611152
  • 109 + 31611043 = 31611152
  • 241 + 31610911 = 31611152
  • 373 + 31610779 = 31611152
  • 379 + 31610773 = 31611152
  • 523 + 31610629 = 31611152
  • 571 + 31610581 = 31611152
  • 613 + 31610539 = 31611152

Showing the first eight; more decompositions exist.
