Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85980, here are decompositions:
- 47 + 85933 = 85980
- 71 + 85909 = 85980
- 127 + 85853 = 85980
- 137 + 85843 = 85980
- 149 + 85831 = 85980
- 151 + 85829 = 85980
- 163 + 85817 = 85980
- 199 + 85781 = 85980
Showing the first eight; more decompositions exist.
