Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28382, here are decompositions:
- 31 + 28351 = 28382
- 73 + 28309 = 28382
- 103 + 28279 = 28382
- 163 + 28219 = 28382
- 181 + 28201 = 28382
- 199 + 28183 = 28382
- 271 + 28111 = 28382
- 283 + 28099 = 28382
Showing the first eight; more decompositions exist.
