Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531544, here are decompositions:

  • 23 + 531521 = 531544
  • 47 + 531497 = 531544
  • 191 + 531353 = 531544
  • 197 + 531347 = 531544
  • 257 + 531287 = 531544
  • 263 + 531281 = 531544
  • 281 + 531263 = 531544
  • 347 + 531197 = 531544

Showing the first eight; more decompositions exist.
