Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465818, here are decompositions:
- 89 + 2147465729 = 2147465818
- 101 + 2147465717 = 2147465818
- 149 + 2147465669 = 2147465818
- 269 + 2147465549 = 2147465818
- 347 + 2147465471 = 2147465818
- 467 + 2147465351 = 2147465818
- 479 + 2147465339 = 2147465818
- 809 + 2147465009 = 2147465818
Showing the first eight; more decompositions exist.
