Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584960, here are decompositions:
- 7 + 31584953 = 31584960
- 13 + 31584947 = 31584960
- 53 + 31584907 = 31584960
- 59 + 31584901 = 31584960
- 73 + 31584887 = 31584960
- 79 + 31584881 = 31584960
- 107 + 31584853 = 31584960
- 131 + 31584829 = 31584960
Showing the first eight; more decompositions exist.
