Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145118, here are decompositions:
- 97 + 145021 = 145118
- 109 + 145009 = 145118
- 151 + 144967 = 145118
- 157 + 144961 = 145118
- 229 + 144889 = 145118
- 271 + 144847 = 145118
- 367 + 144751 = 145118
- 409 + 144709 = 145118
Showing the first eight; more decompositions exist.
