Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490722, here are decompositions:

193 + 2147490529 = 2147490722
271 + 2147490451 = 2147490722
379 + 2147490343 = 2147490722
439 + 2147490283 = 2147490722
613 + 2147490109 = 2147490722
661 + 2147490061 = 2147490722
823 + 2147489899 = 2147490722
1009 + 2147489713 = 2147490722

Showing the first eight; more decompositions exist.

IPv4 address
