Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547296, here are decompositions:
- 29 + 31547267 = 31547296
- 149 + 31547147 = 31547296
- 167 + 31547129 = 31547296
- 233 + 31547063 = 31547296
- 257 + 31547039 = 31547296
- 293 + 31547003 = 31547296
- 359 + 31546937 = 31547296
- 383 + 31546913 = 31547296
Showing the first eight; more decompositions exist.
