Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547194, here are decompositions:
- 17 + 31547177 = 31547194
- 47 + 31547147 = 31547194
- 101 + 31547093 = 31547194
- 131 + 31547063 = 31547194
- 191 + 31547003 = 31547194
- 197 + 31546997 = 31547194
- 257 + 31546937 = 31547194
- 281 + 31546913 = 31547194
Showing the first eight; more decompositions exist.
