Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147477048, here are decompositions:
- 19 + 2147477029 = 2147477048
- 97 + 2147476951 = 2147477048
- 151 + 2147476897 = 2147477048
- 229 + 2147476819 = 2147477048
- 271 + 2147476777 = 2147477048
- 307 + 2147476741 = 2147477048
- 349 + 2147476699 = 2147477048
- 631 + 2147476417 = 2147477048
Showing the first eight; more decompositions exist.
