Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532, here are decompositions:
- 11 + 521 = 532
- 23 + 509 = 532
- 29 + 503 = 532
- 41 + 491 = 532
- 53 + 479 = 532
- 71 + 461 = 532
- 83 + 449 = 532
- 89 + 443 = 532
Showing the first eight; more decompositions exist.
