Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703978, here are decompositions:

  • 7 + 8703971 = 8703978
  • 67 + 8703911 = 8703978
  • 79 + 8703899 = 8703978
  • 89 + 8703889 = 8703978
  • 137 + 8703841 = 8703978
  • 149 + 8703829 = 8703978
  • 167 + 8703811 = 8703978
  • 191 + 8703787 = 8703978

Showing the first eight; more decompositions exist.
