Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521492, here are decompositions:

  • 163 + 521329 = 521492
  • 193 + 521299 = 521492
  • 211 + 521281 = 521492
  • 241 + 521251 = 521492
  • 313 + 521179 = 521492
  • 331 + 521161 = 521492
  • 373 + 521119 = 521492
  • 523 + 520969 = 521492

Showing the first eight; more decompositions exist.
