Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462272, here are decompositions:

  • 5 + 31462267 = 31462272
  • 131 + 31462141 = 31462272
  • 139 + 31462133 = 31462272
  • 251 + 31462021 = 31462272
  • 269 + 31462003 = 31462272
  • 293 + 31461979 = 31462272
  • 311 + 31461961 = 31462272
  • 349 + 31461923 = 31462272

Showing the first eight; more decompositions exist.
