Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758990, here are decompositions:

  • 3 + 8758987 = 8758990
  • 11 + 8758979 = 8758990
  • 59 + 8758931 = 8758990
  • 89 + 8758901 = 8758990
  • 101 + 8758889 = 8758990
  • 113 + 8758877 = 8758990
  • 167 + 8758823 = 8758990
  • 197 + 8758793 = 8758990

Showing the first eight; more decompositions exist.
