Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974978, here are decompositions:
- 5 + 4294974973 = 4294974978
- 59 + 4294974919 = 4294974978
- 61 + 4294974917 = 4294974978
- 97 + 4294974881 = 4294974978
- 167 + 4294974811 = 4294974978
- 241 + 4294974737 = 4294974978
- 331 + 4294974647 = 4294974978
- 337 + 4294974641 = 4294974978
Showing the first eight; more decompositions exist.
