Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689442, here are decompositions:

  • 43 + 8689399 = 8689442
  • 163 + 8689279 = 8689442
  • 193 + 8689249 = 8689442
  • 199 + 8689243 = 8689442
  • 313 + 8689129 = 8689442
  • 331 + 8689111 = 8689442
  • 373 + 8689069 = 8689442
  • 379 + 8689063 = 8689442

Showing the first eight; more decompositions exist.
