Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547136, here are decompositions:
- 7 + 31547129 = 31547136
- 43 + 31547093 = 31547136
- 59 + 31547077 = 31547136
- 73 + 31547063 = 31547136
- 97 + 31547039 = 31547136
- 139 + 31546997 = 31547136
- 149 + 31546987 = 31547136
- 167 + 31546969 = 31547136
Showing the first eight; more decompositions exist.
