Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585162, here are decompositions:
- 3 + 31585159 = 31585162
- 23 + 31585139 = 31585162
- 83 + 31585079 = 31585162
- 101 + 31585061 = 31585162
- 281 + 31584881 = 31585162
- 293 + 31584869 = 31585162
- 353 + 31584809 = 31585162
- 449 + 31584713 = 31585162
Showing the first eight; more decompositions exist.
