Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585932, here are decompositions:
- 29 + 31585903 = 31585932
- 43 + 31585889 = 31585932
- 83 + 31585849 = 31585932
- 109 + 31585823 = 31585932
- 149 + 31585783 = 31585932
- 151 + 31585781 = 31585932
- 181 + 31585751 = 31585932
- 241 + 31585691 = 31585932
Showing the first eight; more decompositions exist.
