Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743168, here are decompositions:
- 29 + 8743139 = 8743168
- 47 + 8743121 = 8743168
- 89 + 8743079 = 8743168
- 101 + 8743067 = 8743168
- 131 + 8743037 = 8743168
- 149 + 8743019 = 8743168
- 167 + 8743001 = 8743168
- 191 + 8742977 = 8743168
Showing the first eight; more decompositions exist.
