Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477018, here are decompositions:
- 67 + 2147476951 = 2147477018
- 199 + 2147476819 = 2147477018
- 229 + 2147476789 = 2147477018
- 241 + 2147476777 = 2147477018
- 277 + 2147476741 = 2147477018
- 331 + 2147476687 = 2147477018
- 499 + 2147476519 = 2147477018
- 601 + 2147476417 = 2147477018
Showing the first eight; more decompositions exist.
