Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491622, here are decompositions:

13 + 2147491609 = 2147491622
19 + 2147491603 = 2147491622
79 + 2147491543 = 2147491622
349 + 2147491273 = 2147491622
373 + 2147491249 = 2147491622
421 + 2147491201 = 2147491622
499 + 2147491123 = 2147491622
541 + 2147491081 = 2147491622

Showing the first eight; more decompositions exist.

IPv4 address
