Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31585032, here are decompositions:
- 13 + 31585019 = 31585032
- 71 + 31584961 = 31585032
- 79 + 31584953 = 31585032
- 131 + 31584901 = 31585032
- 151 + 31584881 = 31585032
- 163 + 31584869 = 31585032
- 179 + 31584853 = 31585032
- 223 + 31584809 = 31585032
Showing the first eight; more decompositions exist.
