Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 434, here are decompositions:
- 3 + 431 = 434
- 13 + 421 = 434
- 37 + 397 = 434
- 61 + 373 = 434
- 67 + 367 = 434
- 97 + 337 = 434
- 103 + 331 = 434
- 127 + 307 = 434
Showing the first eight; more decompositions exist.
