Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470086, here are decompositions:

  • 5 + 2147470081 = 2147470086
  • 19 + 2147470067 = 2147470086
  • 29 + 2147470057 = 2147470086
  • 43 + 2147470043 = 2147470086
  • 59 + 2147470027 = 2147470086
  • 67 + 2147470019 = 2147470086
  • 79 + 2147470007 = 2147470086
  • 103 + 2147469983 = 2147470086

Showing the first eight; more decompositions exist.

IPv4 address
