Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 498, here are decompositions:
- 7 + 491 = 498
- 11 + 487 = 498
- 19 + 479 = 498
- 31 + 467 = 498
- 37 + 461 = 498
- 41 + 457 = 498
- 59 + 439 = 498
- 67 + 431 = 498
Showing the first eight; more decompositions exist.
