Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989970, here are decompositions:

  • 11 + 989959 = 989970
  • 19 + 989951 = 989970
  • 31 + 989939 = 989970
  • 41 + 989929 = 989970
  • 53 + 989917 = 989970
  • 61 + 989909 = 989970
  • 83 + 989887 = 989970
  • 97 + 989873 = 989970

Showing the first eight; more decompositions exist.
