Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618590, here are decompositions:

  • 23 + 8618567 = 8618590
  • 89 + 8618501 = 8618590
  • 107 + 8618483 = 8618590
  • 251 + 8618339 = 8618590
  • 263 + 8618327 = 8618590
  • 293 + 8618297 = 8618590
  • 317 + 8618273 = 8618590
  • 347 + 8618243 = 8618590

Showing the first eight; more decompositions exist.
