Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743618, here are decompositions:

  • 29 + 8743589 = 8743618
  • 47 + 8743571 = 8743618
  • 71 + 8743547 = 8743618
  • 197 + 8743421 = 8743618
  • 239 + 8743379 = 8743618
  • 251 + 8743367 = 8743618
  • 269 + 8743349 = 8743618
  • 449 + 8743169 = 8743618

Showing the first eight; more decompositions exist.
