Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40528, here are decompositions:
- 29 + 40499 = 40528
- 41 + 40487 = 40528
- 101 + 40427 = 40528
- 167 + 40361 = 40528
- 239 + 40289 = 40528
- 251 + 40277 = 40528
- 359 + 40169 = 40528
- 401 + 40127 = 40528
Showing the first eight; more decompositions exist.
