Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147404382, here are decompositions:

73 + 2147404309 = 2147404382
139 + 2147404243 = 2147404382
199 + 2147404183 = 2147404382
229 + 2147404153 = 2147404382
241 + 2147404141 = 2147404382
283 + 2147404099 = 2147404382
523 + 2147403859 = 2147404382
601 + 2147403781 = 2147404382

Showing the first eight; more decompositions exist.

IPv4 address
