Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 9380, here are decompositions:
- 3 + 9377 = 9380
- 31 + 9349 = 9380
- 37 + 9343 = 9380
- 43 + 9337 = 9380
- 61 + 9319 = 9380
- 97 + 9283 = 9380
- 103 + 9277 = 9380
- 139 + 9241 = 9380
Showing the first eight; more decompositions exist.
