Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492090, here are decompositions:

61 + 2147492029 = 2147492090
67 + 2147492023 = 2147492090
193 + 2147491897 = 2147492090
487 + 2147491603 = 2147492090
547 + 2147491543 = 2147492090
613 + 2147491477 = 2147492090
673 + 2147491417 = 2147492090
829 + 2147491261 = 2147492090

Showing the first eight; more decompositions exist.

IPv4 address
