Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147401442, here are decompositions:

73 + 2147401369 = 2147401442
139 + 2147401303 = 2147401442
229 + 2147401213 = 2147401442
271 + 2147401171 = 2147401442
313 + 2147401129 = 2147401442
421 + 2147401021 = 2147401442
499 + 2147400943 = 2147401442
643 + 2147400799 = 2147401442

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 127.254.190.226.

Address: 127.254.190.226
