Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608000, here are decompositions:
- 29 + 31607971 = 31608000
- 31 + 31607969 = 31608000
- 79 + 31607921 = 31608000
- 97 + 31607903 = 31608000
- 103 + 31607897 = 31608000
- 131 + 31607869 = 31608000
- 211 + 31607789 = 31608000
- 283 + 31607717 = 31608000
Showing the first eight; more decompositions exist.
