Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987432, here are decompositions:

  • 41 + 987391 = 987432
  • 71 + 987361 = 987432
  • 79 + 987353 = 987432
  • 139 + 987293 = 987432
  • 181 + 987251 = 987432
  • 223 + 987209 = 987432
  • 233 + 987199 = 987432
  • 239 + 987193 = 987432

Showing the first eight; more decompositions exist.
