Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497280, here are decompositions:

37 + 2147497243 = 2147497280
43 + 2147497237 = 2147497280
79 + 2147497201 = 2147497280
139 + 2147497141 = 2147497280
199 + 2147497081 = 2147497280
241 + 2147497039 = 2147497280
283 + 2147496997 = 2147497280
421 + 2147496859 = 2147497280

Showing the first eight; more decompositions exist.

IPv4 address
