Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978648, here are decompositions:

  • 5 + 978643 = 978648
  • 29 + 978619 = 978648
  • 31 + 978617 = 978648
  • 37 + 978611 = 978648
  • 79 + 978569 = 978648
  • 107 + 978541 = 978648
  • 127 + 978521 = 978648
  • 137 + 978511 = 978648

Showing the first eight; more decompositions exist.
