Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741780, here are decompositions:

  • 31 + 8741749 = 8741780
  • 37 + 8741743 = 8741780
  • 97 + 8741683 = 8741780
  • 139 + 8741641 = 8741780
  • 277 + 8741503 = 8741780
  • 349 + 8741431 = 8741780
  • 379 + 8741401 = 8741780
  • 409 + 8741371 = 8741780

Showing the first eight; more decompositions exist.
