Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670168, here are decompositions:
- 11 + 8670157 = 8670168
- 41 + 8670127 = 8670168
- 61 + 8670107 = 8670168
- 79 + 8670089 = 8670168
- 97 + 8670071 = 8670168
- 127 + 8670041 = 8670168
- 131 + 8670037 = 8670168
- 137 + 8670031 = 8670168
Showing the first eight; more decompositions exist.
