Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486, here are decompositions:
- 7 + 479 = 486
- 19 + 467 = 486
- 23 + 463 = 486
- 29 + 457 = 486
- 37 + 449 = 486
- 43 + 443 = 486
- 47 + 439 = 486
- 53 + 433 = 486
Showing the first eight; more decompositions exist.
