Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485644, here are decompositions:

  • 53 + 2147485591 = 2147485644
  • 71 + 2147485573 = 2147485644
  • 97 + 2147485547 = 2147485644
  • 127 + 2147485517 = 2147485644
  • 193 + 2147485451 = 2147485644
  • 197 + 2147485447 = 2147485644
  • 211 + 2147485433 = 2147485644
  • 223 + 2147485421 = 2147485644

Showing the first eight; more decompositions exist.

IPv4 address
