Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501140, here are decompositions:

  • 11 + 2147501129 = 2147501140
  • 131 + 2147501009 = 2147501140
  • 233 + 2147500907 = 2147501140
  • 251 + 2147500889 = 2147501140
  • 269 + 2147500871 = 2147501140
  • 359 + 2147500781 = 2147501140
  • 443 + 2147500697 = 2147501140
  • 479 + 2147500661 = 2147501140

Showing the first eight; more decompositions exist.
