Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460200, here are decompositions:
- 3 + 31460197 = 31460200
- 71 + 31460129 = 31460200
- 137 + 31460063 = 31460200
- 251 + 31459949 = 31460200
- 263 + 31459937 = 31460200
- 269 + 31459931 = 31460200
- 347 + 31459853 = 31460200
- 353 + 31459847 = 31460200
Showing the first eight; more decompositions exist.
