Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488418, here are decompositions:

7 + 2147488411 = 2147488418
37 + 2147488381 = 2147488418
139 + 2147488279 = 2147488418
307 + 2147488111 = 2147488418
409 + 2147488009 = 2147488418
487 + 2147487931 = 2147488418
547 + 2147487871 = 2147488418
601 + 2147487817 = 2147488418

Showing the first eight; more decompositions exist.

IPv4 address
