Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489228, here are decompositions:

139 + 2147489089 = 2147489228
151 + 2147489077 = 2147489228
211 + 2147489017 = 2147489228
487 + 2147488741 = 2147489228
811 + 2147488417 = 2147489228
1117 + 2147488111 = 2147489228
1201 + 2147488027 = 2147489228
1297 + 2147487931 = 2147489228

Showing the first eight; more decompositions exist.

IPv4 address
