Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85218, here are decompositions:
- 5 + 85213 = 85218
- 17 + 85201 = 85218
- 19 + 85199 = 85218
- 59 + 85159 = 85218
- 71 + 85147 = 85218
- 97 + 85121 = 85218
- 109 + 85109 = 85218
- 127 + 85091 = 85218
Showing the first eight; more decompositions exist.
