Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489692, here are decompositions:

41 + 2147489651 = 2147489692
53 + 2147489639 = 2147489692
113 + 2147489579 = 2147489692
149 + 2147489543 = 2147489692
251 + 2147489441 = 2147489692
269 + 2147489423 = 2147489692
401 + 2147489291 = 2147489692
449 + 2147489243 = 2147489692

Showing the first eight; more decompositions exist.

IPv4 address
