Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465742, here are decompositions:
- 11 + 2147465731 = 2147465742
- 13 + 2147465729 = 2147465742
- 41 + 2147465701 = 2147465742
- 43 + 2147465699 = 2147465742
- 73 + 2147465669 = 2147465742
- 179 + 2147465563 = 2147465742
- 193 + 2147465549 = 2147465742
- 211 + 2147465531 = 2147465742
Showing the first eight; more decompositions exist.
