Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61458, here are decompositions:
- 17 + 61441 = 61458
- 41 + 61417 = 61458
- 79 + 61379 = 61458
- 101 + 61357 = 61458
- 127 + 61331 = 61458
- 167 + 61291 = 61458
- 197 + 61261 = 61458
- 227 + 61231 = 61458
Showing the first eight; more decompositions exist.
