Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978978, here are decompositions:
- 5 + 4294978973 = 4294978978
- 29 + 4294978949 = 4294978978
- 167 + 4294978811 = 4294978978
- 179 + 4294978799 = 4294978978
- 197 + 4294978781 = 4294978978
- 317 + 4294978661 = 4294978978
- 419 + 4294978559 = 4294978978
- 461 + 4294978517 = 4294978978
Showing the first eight; more decompositions exist.
