Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12960, here are decompositions:

  • 7 + 12953 = 12960
  • 19 + 12941 = 12960
  • 37 + 12923 = 12960
  • 41 + 12919 = 12960
  • 43 + 12917 = 12960
  • 53 + 12907 = 12960
  • 61 + 12899 = 12960
  • 67 + 12893 = 12960

Showing the first eight; more decompositions exist.
