Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648670, here are decompositions:
- 113 + 8648557 = 8648670
- 127 + 8648543 = 8648670
- 137 + 8648533 = 8648670
- 139 + 8648531 = 8648670
- 157 + 8648513 = 8648670
- 211 + 8648459 = 8648670
- 223 + 8648447 = 8648670
- 257 + 8648413 = 8648670
Showing the first eight; more decompositions exist.
