Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28446, here are decompositions:
- 7 + 28439 = 28446
- 13 + 28433 = 28446
- 17 + 28429 = 28446
- 37 + 28409 = 28446
- 43 + 28403 = 28446
- 53 + 28393 = 28446
- 59 + 28387 = 28446
- 97 + 28349 = 28446
Showing the first eight; more decompositions exist.
