Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736168, here are decompositions:
- 29 + 8736139 = 8736168
- 41 + 8736127 = 8736168
- 59 + 8736109 = 8736168
- 71 + 8736097 = 8736168
- 79 + 8736089 = 8736168
- 107 + 8736061 = 8736168
- 109 + 8736059 = 8736168
- 127 + 8736041 = 8736168
Showing the first eight; more decompositions exist.
