Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675780, here are decompositions:

  • 13 + 8675767 = 8675780
  • 31 + 8675749 = 8675780
  • 37 + 8675743 = 8675780
  • 103 + 8675677 = 8675780
  • 109 + 8675671 = 8675780
  • 271 + 8675509 = 8675780
  • 277 + 8675503 = 8675780
  • 307 + 8675473 = 8675780

Showing the first eight; more decompositions exist.
