Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615404, here are decompositions:

  • 71 + 8615333 = 8615404
  • 131 + 8615273 = 8615404
  • 137 + 8615267 = 8615404
  • 167 + 8615237 = 8615404
  • 173 + 8615231 = 8615404
  • 227 + 8615177 = 8615404
  • 353 + 8615051 = 8615404
  • 431 + 8614973 = 8615404

Showing the first eight; more decompositions exist.
