Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670648, here are decompositions:
- 11 + 8670637 = 8670648
- 29 + 8670619 = 8670648
- 37 + 8670611 = 8670648
- 59 + 8670589 = 8670648
- 89 + 8670559 = 8670648
- 97 + 8670551 = 8670648
- 139 + 8670509 = 8670648
- 149 + 8670499 = 8670648
Showing the first eight; more decompositions exist.
