Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85648, here are decompositions:
- 5 + 85643 = 85648
- 29 + 85619 = 85648
- 41 + 85607 = 85648
- 47 + 85601 = 85648
- 71 + 85577 = 85648
- 131 + 85517 = 85648
- 179 + 85469 = 85648
- 197 + 85451 = 85648
Showing the first eight; more decompositions exist.
