Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147423884, here are decompositions:
- 3 + 2147423881 = 2147423884
- 113 + 2147423771 = 2147423884
- 131 + 2147423753 = 2147423884
- 167 + 2147423717 = 2147423884
- 173 + 2147423711 = 2147423884
- 191 + 2147423693 = 2147423884
- 233 + 2147423651 = 2147423884
- 257 + 2147423627 = 2147423884
Showing the first eight; more decompositions exist.
