Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9142, here are decompositions:
- 5 + 9137 = 9142
- 83 + 9059 = 9142
- 101 + 9041 = 9142
- 113 + 9029 = 9142
- 131 + 9011 = 9142
- 173 + 8969 = 9142
- 179 + 8963 = 9142
- 191 + 8951 = 9142
Showing the first eight; more decompositions exist.
