Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484148, here are decompositions:

107 + 2147484041 = 2147484148
149 + 2147483999 = 2147484148
197 + 2147483951 = 2147484148
281 + 2147483867 = 2147484148
569 + 2147483579 = 2147484148
599 + 2147483549 = 2147484148
659 + 2147483489 = 2147484148
911 + 2147483237 = 2147484148

Showing the first eight; more decompositions exist.

IPv4 address
