Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128294, here are decompositions:
- 3 + 128291 = 128294
- 7 + 128287 = 128294
- 37 + 128257 = 128294
- 73 + 128221 = 128294
- 181 + 128113 = 128294
- 241 + 128053 = 128294
- 373 + 127921 = 128294
- 421 + 127873 = 128294
Showing the first eight; more decompositions exist.
