Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155204, here are decompositions:
- 3 + 155201 = 155204
- 13 + 155191 = 155204
- 37 + 155167 = 155204
- 43 + 155161 = 155204
- 67 + 155137 = 155204
- 157 + 155047 = 155204
- 223 + 154981 = 155204
- 271 + 154933 = 155204
Showing the first eight; more decompositions exist.
