Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491900, here are decompositions:

3 + 2147491897 = 2147491900
167 + 2147491733 = 2147491900
293 + 2147491607 = 2147491900
317 + 2147491583 = 2147491900
347 + 2147491553 = 2147491900
353 + 2147491547 = 2147491900
383 + 2147491517 = 2147491900
557 + 2147491343 = 2147491900

Showing the first eight; more decompositions exist.

IPv4 address
