Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494, here are decompositions:
- 3 + 491 = 494
- 7 + 487 = 494
- 31 + 463 = 494
- 37 + 457 = 494
- 61 + 433 = 494
- 73 + 421 = 494
- 97 + 397 = 494
- 127 + 367 = 494
Showing the first eight; more decompositions exist.
