Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185250, here are decompositions:
- 7 + 185243 = 185250
- 17 + 185233 = 185250
- 29 + 185221 = 185250
- 61 + 185189 = 185250
- 67 + 185183 = 185250
- 73 + 185177 = 185250
- 83 + 185167 = 185250
- 89 + 185161 = 185250
Showing the first eight; more decompositions exist.
