Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 430, here are decompositions:
- 11 + 419 = 430
- 29 + 401 = 430
- 41 + 389 = 430
- 47 + 383 = 430
- 71 + 359 = 430
- 83 + 347 = 430
- 113 + 317 = 430
- 137 + 293 = 430
Showing the first eight; more decompositions exist.
