Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547316, here are decompositions:
- 13 + 31547303 = 31547316
- 19 + 31547297 = 31547316
- 29 + 31547287 = 31547316
- 107 + 31547209 = 31547316
- 113 + 31547203 = 31547316
- 139 + 31547177 = 31547316
- 173 + 31547143 = 31547316
- 223 + 31547093 = 31547316
Showing the first eight; more decompositions exist.
