Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664886, here are decompositions:

  • 17 + 8664869 = 8664886
  • 23 + 8664863 = 8664886
  • 29 + 8664857 = 8664886
  • 359 + 8664527 = 8664886
  • 467 + 8664419 = 8664886
  • 509 + 8664377 = 8664886
  • 557 + 8664329 = 8664886
  • 569 + 8664317 = 8664886

Showing the first eight; more decompositions exist.
