Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57242, here are decompositions:

  • 19 + 57223 = 57242
  • 79 + 57163 = 57242
  • 103 + 57139 = 57242
  • 313 + 56929 = 57242
  • 331 + 56911 = 57242
  • 349 + 56893 = 57242
  • 421 + 56821 = 57242
  • 433 + 56809 = 57242

Showing the first eight; more decompositions exist.
