Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427928, here are decompositions:
- 5 + 2147427923 = 2147427928
- 17 + 2147427911 = 2147427928
- 89 + 2147427839 = 2147427928
- 101 + 2147427827 = 2147427928
- 131 + 2147427797 = 2147427928
- 227 + 2147427701 = 2147427928
- 251 + 2147427677 = 2147427928
- 281 + 2147427647 = 2147427928
Showing the first eight; more decompositions exist.
