Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720358, here are decompositions:

  • 11 + 8720347 = 8720358
  • 19 + 8720339 = 8720358
  • 37 + 8720321 = 8720358
  • 41 + 8720317 = 8720358
  • 47 + 8720311 = 8720358
  • 131 + 8720227 = 8720358
  • 167 + 8720191 = 8720358
  • 181 + 8720177 = 8720358

Showing the first eight; more decompositions exist.
