Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28230, here are decompositions:
- 11 + 28219 = 28230
- 19 + 28211 = 28230
- 29 + 28201 = 28230
- 47 + 28183 = 28230
- 67 + 28163 = 28230
- 79 + 28151 = 28230
- 107 + 28123 = 28230
- 131 + 28099 = 28230
Showing the first eight; more decompositions exist.
