Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725988, here are decompositions:

  • 157 + 8725831 = 8725988
  • 307 + 8725681 = 8725988
  • 331 + 8725657 = 8725988
  • 367 + 8725621 = 8725988
  • 379 + 8725609 = 8725988
  • 421 + 8725567 = 8725988
  • 457 + 8725531 = 8725988
  • 499 + 8725489 = 8725988

Showing the first eight; more decompositions exist.
