Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294966978, here are decompositions:
- 101 + 4294966877 = 4294966978
- 149 + 4294966829 = 4294966978
- 311 + 4294966667 = 4294966978
- 317 + 4294966661 = 4294966978
- 359 + 4294966619 = 4294966978
- 641 + 4294966337 = 4294966978
- 761 + 4294966217 = 4294966978
- 857 + 4294966121 = 4294966978
Showing the first eight; more decompositions exist.
