Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975220, here are decompositions:
- 73 + 4294975147 = 4294975220
- 97 + 4294975123 = 4294975220
- 103 + 4294975117 = 4294975220
- 127 + 4294975093 = 4294975220
- 163 + 4294975057 = 4294975220
- 223 + 4294974997 = 4294975220
- 229 + 4294974991 = 4294975220
- 307 + 4294974913 = 4294975220
Showing the first eight; more decompositions exist.
