Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147465760, here are decompositions:
- 17 + 2147465743 = 2147465760
- 29 + 2147465731 = 2147465760
- 31 + 2147465729 = 2147465760
- 43 + 2147465717 = 2147465760
- 53 + 2147465707 = 2147465760
- 59 + 2147465701 = 2147465760
- 61 + 2147465699 = 2147465760
- 113 + 2147465647 = 2147465760
Showing the first eight; more decompositions exist.
