Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584000, here are decompositions:
- 11 + 31583989 = 31584000
- 17 + 31583983 = 31584000
- 29 + 31583971 = 31584000
- 59 + 31583941 = 31584000
- 79 + 31583921 = 31584000
- 89 + 31583911 = 31584000
- 103 + 31583897 = 31584000
- 137 + 31583863 = 31584000
Showing the first eight; more decompositions exist.
