Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515382, here are decompositions:

  • 5 + 515377 = 515382
  • 11 + 515371 = 515382
  • 13 + 515369 = 515382
  • 31 + 515351 = 515382
  • 59 + 515323 = 515382
  • 71 + 515311 = 515382
  • 89 + 515293 = 515382
  • 103 + 515279 = 515382

Showing the first eight; more decompositions exist.
