Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 606, here are decompositions:

  • 5 + 601 = 606
  • 7 + 599 = 606
  • 13 + 593 = 606
  • 19 + 587 = 606
  • 29 + 577 = 606
  • 37 + 569 = 606
  • 43 + 563 = 606
  • 59 + 547 = 606

Showing the first eight; more decompositions exist.
