Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28450, here are decompositions:
- 3 + 28447 = 28450
- 11 + 28439 = 28450
- 17 + 28433 = 28450
- 41 + 28409 = 28450
- 47 + 28403 = 28450
- 101 + 28349 = 28450
- 131 + 28319 = 28450
- 167 + 28283 = 28450
Showing the first eight; more decompositions exist.
