Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68430, here are decompositions:

  • 31 + 68399 = 68430
  • 41 + 68389 = 68430
  • 59 + 68371 = 68430
  • 79 + 68351 = 68430
  • 101 + 68329 = 68430
  • 149 + 68281 = 68430
  • 151 + 68279 = 68430
  • 191 + 68239 = 68430

Showing the first eight; more decompositions exist.
