Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961928, here are decompositions:
- 7 + 4294961921 = 4294961928
- 31 + 4294961897 = 4294961928
- 67 + 4294961861 = 4294961928
- 137 + 4294961791 = 4294961928
- 151 + 4294961777 = 4294961928
- 181 + 4294961747 = 4294961928
- 331 + 4294961597 = 4294961928
- 349 + 4294961579 = 4294961928
Showing the first eight; more decompositions exist.
