Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85242, here are decompositions:
- 5 + 85237 = 85242
- 13 + 85229 = 85242
- 19 + 85223 = 85242
- 29 + 85213 = 85242
- 41 + 85201 = 85242
- 43 + 85199 = 85242
- 83 + 85159 = 85242
- 109 + 85133 = 85242
Showing the first eight; more decompositions exist.
