Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515394, here are decompositions:

  • 13 + 515381 = 515394
  • 17 + 515377 = 515394
  • 23 + 515371 = 515394
  • 37 + 515357 = 515394
  • 43 + 515351 = 515394
  • 71 + 515323 = 515394
  • 83 + 515311 = 515394
  • 101 + 515293 = 515394

Showing the first eight; more decompositions exist.
