Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145984, here are decompositions:
- 17 + 145967 = 145984
- 53 + 145931 = 145984
- 227 + 145757 = 145984
- 263 + 145721 = 145984
- 281 + 145703 = 145984
- 347 + 145637 = 145984
- 383 + 145601 = 145984
- 467 + 145517 = 145984
Showing the first eight; more decompositions exist.
