Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489492, here are decompositions:

19 + 2147489473 = 2147489492
193 + 2147489299 = 2147489492
229 + 2147489263 = 2147489492
349 + 2147489143 = 2147489492
409 + 2147489083 = 2147489492
433 + 2147489059 = 2147489492
751 + 2147488741 = 2147489492
919 + 2147488573 = 2147489492

Showing the first eight; more decompositions exist.

IPv4 address
