Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493618, here are decompositions:

19 + 2147493599 = 2147493618
29 + 2147493589 = 2147493618
71 + 2147493547 = 2147493618
139 + 2147493479 = 2147493618
227 + 2147493391 = 2147493618
307 + 2147493311 = 2147493618
317 + 2147493301 = 2147493618
337 + 2147493281 = 2147493618

Showing the first eight; more decompositions exist.

IPv4 address
