Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471304, here are decompositions:

  • 97 + 31471207 = 31471304
  • 157 + 31471147 = 31471304
  • 181 + 31471123 = 31471304
  • 211 + 31471093 = 31471304
  • 307 + 31470997 = 31471304
  • 313 + 31470991 = 31471304
  • 457 + 31470847 = 31471304
  • 523 + 31470781 = 31471304

Showing the first eight; more decompositions exist.
