Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147458006, here are decompositions:

  • 47 + 2147457959 = 2147458006
  • 167 + 2147457839 = 2147458006
  • 257 + 2147457749 = 2147458006
  • 269 + 2147457737 = 2147458006
  • 347 + 2147457659 = 2147458006
  • 383 + 2147457623 = 2147458006
  • 443 + 2147457563 = 2147458006
  • 569 + 2147457437 = 2147458006

Showing the first eight; more decompositions exist.
