Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490476, here are decompositions:

13 + 2147490463 = 2147490476
193 + 2147490283 = 2147490476
367 + 2147490109 = 2147490476
577 + 2147489899 = 2147490476
823 + 2147489653 = 2147490476
1039 + 2147489437 = 2147490476
1129 + 2147489347 = 2147490476
1213 + 2147489263 = 2147490476

Showing the first eight; more decompositions exist.

IPv4 address
