Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85372, here are decompositions:
- 3 + 85369 = 85372
- 11 + 85361 = 85372
- 41 + 85331 = 85372
- 59 + 85313 = 85372
- 113 + 85259 = 85372
- 149 + 85223 = 85372
- 173 + 85199 = 85372
- 179 + 85193 = 85372
Showing the first eight; more decompositions exist.
