Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9180, here are decompositions:
- 7 + 9173 = 9180
- 19 + 9161 = 9180
- 23 + 9157 = 9180
- 29 + 9151 = 9180
- 43 + 9137 = 9180
- 47 + 9133 = 9180
- 53 + 9127 = 9180
- 71 + 9109 = 9180
Showing the first eight; more decompositions exist.
