Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736428, here are decompositions:

  • 61 + 8736367 = 8736428
  • 229 + 8736199 = 8736428
  • 241 + 8736187 = 8736428
  • 331 + 8736097 = 8736428
  • 367 + 8736061 = 8736428
  • 457 + 8735971 = 8736428
  • 487 + 8735941 = 8736428
  • 577 + 8735851 = 8736428

Showing the first eight; more decompositions exist.
