Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669040, here are decompositions:
- 13 + 8669027 = 8669040
- 47 + 8668993 = 8669040
- 67 + 8668973 = 8669040
- 73 + 8668967 = 8669040
- 89 + 8668951 = 8669040
- 139 + 8668901 = 8669040
- 151 + 8668889 = 8669040
- 167 + 8668873 = 8669040
Showing the first eight; more decompositions exist.
