Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4418, here are decompositions:

  • 61 + 4357 = 4418
  • 79 + 4339 = 4418
  • 157 + 4261 = 4418
  • 199 + 4219 = 4418
  • 241 + 4177 = 4418
  • 307 + 4111 = 4418
  • 367 + 4051 = 4418
  • 397 + 4021 = 4418

Showing the first eight; more decompositions exist.
