Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85230, here are decompositions:
- 7 + 85223 = 85230
- 17 + 85213 = 85230
- 29 + 85201 = 85230
- 31 + 85199 = 85230
- 37 + 85193 = 85230
- 71 + 85159 = 85230
- 83 + 85147 = 85230
- 97 + 85133 = 85230
Showing the first eight; more decompositions exist.
