Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491814, here are decompositions:

211 + 2147491603 = 2147491814
241 + 2147491573 = 2147491814
271 + 2147491543 = 2147491814
277 + 2147491537 = 2147491814
337 + 2147491477 = 2147491814
397 + 2147491417 = 2147491814
541 + 2147491273 = 2147491814
577 + 2147491237 = 2147491814

Showing the first eight; more decompositions exist.

IPv4 address
