Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147467478, here are decompositions:

  • 7 + 2147467471 = 2147467478
  • 139 + 2147467339 = 2147467478
  • 151 + 2147467327 = 2147467478
  • 157 + 2147467321 = 2147467478
  • 421 + 2147467057 = 2147467478
  • 487 + 2147466991 = 2147467478
  • 547 + 2147466931 = 2147467478
  • 631 + 2147466847 = 2147467478

Showing the first eight; more decompositions exist.
