Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491590, here are decompositions:

7 + 2147491583 = 2147491590
17 + 2147491573 = 2147491590
31 + 2147491559 = 2147491590
37 + 2147491553 = 2147491590
43 + 2147491547 = 2147491590
47 + 2147491543 = 2147491590
53 + 2147491537 = 2147491590
73 + 2147491517 = 2147491590

Showing the first eight; more decompositions exist.

IPv4 address
