Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562342, here are decompositions:

  • 13 + 31562329 = 31562342
  • 43 + 31562299 = 31562342
  • 61 + 31562281 = 31562342
  • 79 + 31562263 = 31562342
  • 223 + 31562119 = 31562342
  • 349 + 31561993 = 31562342
  • 373 + 31561969 = 31562342
  • 439 + 31561903 = 31562342

Showing the first eight; more decompositions exist.
