Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485428, here are decompositions:

5 + 2147485423 = 2147485428
7 + 2147485421 = 2147485428
17 + 2147485411 = 2147485428
47 + 2147485381 = 2147485428
59 + 2147485369 = 2147485428
71 + 2147485357 = 2147485428
167 + 2147485261 = 2147485428
181 + 2147485247 = 2147485428

Showing the first eight; more decompositions exist.

IPv4 address
