Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482186, here are decompositions:
- 7 + 31482179 = 31482186
- 13 + 31482173 = 31482186
- 17 + 31482169 = 31482186
- 19 + 31482167 = 31482186
- 67 + 31482119 = 31482186
- 83 + 31482103 = 31482186
- 89 + 31482097 = 31482186
- 97 + 31482089 = 31482186
Showing the first eight; more decompositions exist.
