Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748168, here are decompositions:
- 7 + 8748161 = 8748168
- 31 + 8748137 = 8748168
- 59 + 8748109 = 8748168
- 71 + 8748097 = 8748168
- 137 + 8748031 = 8748168
- 151 + 8748017 = 8748168
- 157 + 8748011 = 8748168
- 167 + 8748001 = 8748168
Showing the first eight; more decompositions exist.
