Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20504, here are decompositions:
- 61 + 20443 = 20504
- 73 + 20431 = 20504
- 97 + 20407 = 20504
- 151 + 20353 = 20504
- 157 + 20347 = 20504
- 163 + 20341 = 20504
- 181 + 20323 = 20504
- 271 + 20233 = 20504
Showing the first eight; more decompositions exist.
