Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423858, here are decompositions:
- 7 + 2147423851 = 2147423858
- 37 + 2147423821 = 2147423858
- 157 + 2147423701 = 2147423858
- 199 + 2147423659 = 2147423858
- 211 + 2147423647 = 2147423858
- 271 + 2147423587 = 2147423858
- 397 + 2147423461 = 2147423858
- 577 + 2147423281 = 2147423858
Showing the first eight; more decompositions exist.
