Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72922, here are decompositions:
- 11 + 72911 = 72922
- 29 + 72893 = 72922
- 53 + 72869 = 72922
- 233 + 72689 = 72922
- 251 + 72671 = 72922
- 389 + 72533 = 72922
- 419 + 72503 = 72922
- 461 + 72461 = 72922
Showing the first eight; more decompositions exist.
