Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145654, here are decompositions:
- 11 + 145643 = 145654
- 17 + 145637 = 145654
- 53 + 145601 = 145654
- 107 + 145547 = 145654
- 137 + 145517 = 145654
- 167 + 145487 = 145654
- 191 + 145463 = 145654
- 263 + 145391 = 145654
Showing the first eight; more decompositions exist.
