Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492992, here are decompositions:

  • 53 + 2147492939 = 2147492992
  • 149 + 2147492843 = 2147492992
  • 233 + 2147492759 = 2147492992
  • 251 + 2147492741 = 2147492992
  • 353 + 2147492639 = 2147492992
  • 383 + 2147492609 = 2147492992
  • 401 + 2147492591 = 2147492992
  • 503 + 2147492489 = 2147492992

Showing the first eight; more decompositions exist.

IPv4 address
