Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294961856, here are decompositions:
- 13 + 4294961843 = 4294961856
- 47 + 4294961809 = 4294961856
- 79 + 4294961777 = 4294961856
- 89 + 4294961767 = 4294961856
- 109 + 4294961747 = 4294961856
- 149 + 4294961707 = 4294961856
- 193 + 4294961663 = 4294961856
- 233 + 4294961623 = 4294961856
Showing the first eight; more decompositions exist.
