Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466786, here are decompositions:

  • 103 + 2147466683 = 2147466786
  • 107 + 2147466679 = 2147466786
  • 197 + 2147466589 = 2147466786
  • 239 + 2147466547 = 2147466786
  • 307 + 2147466479 = 2147466786
  • 337 + 2147466449 = 2147466786
  • 347 + 2147466439 = 2147466786
  • 359 + 2147466427 = 2147466786

Showing the first eight; more decompositions exist.
