Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423760, here are decompositions:
- 7 + 2147423753 = 2147423760
- 17 + 2147423743 = 2147423760
- 43 + 2147423717 = 2147423760
- 47 + 2147423713 = 2147423760
- 59 + 2147423701 = 2147423760
- 67 + 2147423693 = 2147423760
- 71 + 2147423689 = 2147423760
- 89 + 2147423671 = 2147423760
Showing the first eight; more decompositions exist.
