Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488946, here are decompositions:

79 + 2147488867 = 2147488946
367 + 2147488579 = 2147488946
373 + 2147488573 = 2147488946
613 + 2147488333 = 2147488946
919 + 2147488027 = 2147488946
937 + 2147488009 = 2147488946
1039 + 2147487907 = 2147488946
1117 + 2147487829 = 2147488946

Showing the first eight; more decompositions exist.

IPv4 address
