Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642088, here are decompositions:
- 11 + 8642077 = 8642088
- 29 + 8642059 = 8642088
- 31 + 8642057 = 8642088
- 61 + 8642027 = 8642088
- 97 + 8641991 = 8642088
- 101 + 8641987 = 8642088
- 131 + 8641957 = 8642088
- 139 + 8641949 = 8642088
Showing the first eight; more decompositions exist.
