Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147455048, here are decompositions:
- 5 + 2147455043 = 2147455048
- 29 + 2147455019 = 2147455048
- 107 + 2147454941 = 2147455048
- 197 + 2147454851 = 2147455048
- 239 + 2147454809 = 2147455048
- 419 + 2147454629 = 2147455048
- 509 + 2147454539 = 2147455048
- 1049 + 2147453999 = 2147455048
Showing the first eight; more decompositions exist.
