Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584908, here are decompositions:
- 7 + 31584901 = 31584908
- 79 + 31584829 = 31584908
- 139 + 31584769 = 31584908
- 151 + 31584757 = 31584908
- 211 + 31584697 = 31584908
- 241 + 31584667 = 31584908
- 307 + 31584601 = 31584908
- 331 + 31584577 = 31584908
Showing the first eight; more decompositions exist.
