Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997408, here are decompositions:

  • 17 + 997391 = 997408
  • 29 + 997379 = 997408
  • 89 + 997319 = 997408
  • 101 + 997307 = 997408
  • 149 + 997259 = 997408
  • 257 + 997151 = 997408
  • 311 + 997097 = 997408
  • 317 + 997091 = 997408

Showing the first eight; more decompositions exist.
