Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 508, here are decompositions:
- 5 + 503 = 508
- 17 + 491 = 508
- 29 + 479 = 508
- 41 + 467 = 508
- 47 + 461 = 508
- 59 + 449 = 508
- 89 + 419 = 508
- 107 + 401 = 508
Showing the first eight; more decompositions exist.
