Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589270, here are decompositions:

  • 19 + 31589251 = 31589270
  • 73 + 31589197 = 31589270
  • 103 + 31589167 = 31589270
  • 151 + 31589119 = 31589270
  • 277 + 31588993 = 31589270
  • 313 + 31588957 = 31589270
  • 337 + 31588933 = 31589270
  • 373 + 31588897 = 31589270

Showing the first eight; more decompositions exist.
