Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 470, here are decompositions:
- 3 + 467 = 470
- 7 + 463 = 470
- 13 + 457 = 470
- 31 + 439 = 470
- 37 + 433 = 470
- 61 + 409 = 470
- 73 + 397 = 470
- 97 + 373 = 470
Showing the first eight; more decompositions exist.
