Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6558, here are decompositions:

  • 5 + 6553 = 6558
  • 7 + 6551 = 6558
  • 11 + 6547 = 6558
  • 29 + 6529 = 6558
  • 37 + 6521 = 6558
  • 67 + 6491 = 6558
  • 89 + 6469 = 6558
  • 107 + 6451 = 6558

Showing the first eight; more decompositions exist.
