Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584446, here are decompositions:

53 + 2147584393 = 2147584446
103 + 2147584343 = 2147584446
193 + 2147584253 = 2147584446
197 + 2147584249 = 2147584446
383 + 2147584063 = 2147584446
389 + 2147584057 = 2147584446
433 + 2147584013 = 2147584446
457 + 2147583989 = 2147584446

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 128.1.137.190.
