Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690942, here are decompositions:

  • 229 + 8690713 = 8690942
  • 283 + 8690659 = 8690942
  • 331 + 8690611 = 8690942
  • 349 + 8690593 = 8690942
  • 571 + 8690371 = 8690942
  • 739 + 8690203 = 8690942
  • 751 + 8690191 = 8690942
  • 769 + 8690173 = 8690942

Showing the first eight; more decompositions exist.
