Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28204, here are decompositions:
- 3 + 28201 = 28204
- 23 + 28181 = 28204
- 41 + 28163 = 28204
- 53 + 28151 = 28204
- 107 + 28097 = 28204
- 173 + 28031 = 28204
- 251 + 27953 = 28204
- 257 + 27947 = 28204
Showing the first eight; more decompositions exist.
