Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642124, here are decompositions:
- 5 + 8642119 = 8642124
- 13 + 8642111 = 8642124
- 17 + 8642107 = 8642124
- 47 + 8642077 = 8642124
- 61 + 8642063 = 8642124
- 67 + 8642057 = 8642124
- 97 + 8642027 = 8642124
- 137 + 8641987 = 8642124
Showing the first eight; more decompositions exist.
