Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758780, here are decompositions:

  • 3 + 8758777 = 8758780
  • 47 + 8758733 = 8758780
  • 59 + 8758721 = 8758780
  • 83 + 8758697 = 8758780
  • 197 + 8758583 = 8758780
  • 269 + 8758511 = 8758780
  • 281 + 8758499 = 8758780
  • 347 + 8758433 = 8758780

Showing the first eight; more decompositions exist.
