Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562350, here are decompositions:

  • 3 + 31562347 = 31562350
  • 59 + 31562291 = 31562350
  • 89 + 31562261 = 31562350
  • 107 + 31562243 = 31562350
  • 137 + 31562213 = 31562350
  • 233 + 31562117 = 31562350
  • 251 + 31562099 = 31562350
  • 257 + 31562093 = 31562350

Showing the first eight; more decompositions exist.
