Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423830, here are decompositions:
- 59 + 2147423771 = 2147423830
- 113 + 2147423717 = 2147423830
- 137 + 2147423693 = 2147423830
- 179 + 2147423651 = 2147423830
- 257 + 2147423573 = 2147423830
- 317 + 2147423513 = 2147423830
- 353 + 2147423477 = 2147423830
- 467 + 2147423363 = 2147423830
Showing the first eight; more decompositions exist.
