Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70870, here are decompositions:

  • 3 + 70867 = 70870
  • 17 + 70853 = 70870
  • 29 + 70841 = 70870
  • 47 + 70823 = 70870
  • 101 + 70769 = 70870
  • 251 + 70619 = 70870
  • 263 + 70607 = 70870
  • 281 + 70589 = 70870

Showing the first eight; more decompositions exist.
