Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 548, here are decompositions:
- 7 + 541 = 548
- 61 + 487 = 548
- 109 + 439 = 548
- 127 + 421 = 548
- 139 + 409 = 548
- 151 + 397 = 548
- 181 + 367 = 548
- 199 + 349 = 548
Showing the first eight; more decompositions exist.
