Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294962978, here are decompositions:
- 67 + 4294962911 = 4294962978
- 79 + 4294962899 = 4294962978
- 151 + 4294962827 = 4294962978
- 199 + 4294962779 = 4294962978
- 227 + 4294962751 = 4294962978
- 337 + 4294962641 = 4294962978
- 349 + 4294962629 = 4294962978
- 359 + 4294962619 = 4294962978
Showing the first eight; more decompositions exist.
