Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28476, here are decompositions:
- 13 + 28463 = 28476
- 29 + 28447 = 28476
- 37 + 28439 = 28476
- 43 + 28433 = 28476
- 47 + 28429 = 28476
- 67 + 28409 = 28476
- 73 + 28403 = 28476
- 83 + 28393 = 28476
Showing the first eight; more decompositions exist.
