Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128204, here are decompositions:
- 3 + 128201 = 128204
- 31 + 128173 = 128204
- 151 + 128053 = 128204
- 157 + 128047 = 128204
- 283 + 127921 = 128204
- 331 + 127873 = 128204
- 337 + 127867 = 128204
- 367 + 127837 = 128204
Showing the first eight; more decompositions exist.
