Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427792, here are decompositions:
- 11 + 2147427781 = 2147427792
- 89 + 2147427703 = 2147427792
- 113 + 2147427679 = 2147427792
- 149 + 2147427643 = 2147427792
- 199 + 2147427593 = 2147427792
- 229 + 2147427563 = 2147427792
- 241 + 2147427551 = 2147427792
- 563 + 2147427229 = 2147427792
Showing the first eight; more decompositions exist.
