Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547250, here are decompositions:
- 19 + 31547231 = 31547250
- 41 + 31547209 = 31547250
- 47 + 31547203 = 31547250
- 73 + 31547177 = 31547250
- 89 + 31547161 = 31547250
- 103 + 31547147 = 31547250
- 107 + 31547143 = 31547250
- 149 + 31547101 = 31547250
Showing the first eight; more decompositions exist.
