Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758878, here are decompositions:

  • 17 + 8758861 = 8758878
  • 31 + 8758847 = 8758878
  • 59 + 8758819 = 8758878
  • 97 + 8758781 = 8758878
  • 101 + 8758777 = 8758878
  • 131 + 8758747 = 8758878
  • 157 + 8758721 = 8758878
  • 181 + 8758697 = 8758878

Showing the first eight; more decompositions exist.
