Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726430, here are decompositions:

  • 29 + 8726401 = 8726430
  • 47 + 8726383 = 8726430
  • 67 + 8726363 = 8726430
  • 71 + 8726359 = 8726430
  • 73 + 8726357 = 8726430
  • 79 + 8726351 = 8726430
  • 101 + 8726329 = 8726430
  • 107 + 8726323 = 8726430

Showing the first eight; more decompositions exist.
