Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726406, here are decompositions:

  • 5 + 8726401 = 8726406
  • 23 + 8726383 = 8726406
  • 43 + 8726363 = 8726406
  • 47 + 8726359 = 8726406
  • 83 + 8726323 = 8726406
  • 149 + 8726257 = 8726406
  • 163 + 8726243 = 8726406
  • 167 + 8726239 = 8726406

Showing the first eight; more decompositions exist.
