Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85670, here are decompositions:
- 3 + 85667 = 85670
- 31 + 85639 = 85670
- 43 + 85627 = 85670
- 73 + 85597 = 85670
- 139 + 85531 = 85670
- 157 + 85513 = 85670
- 223 + 85447 = 85670
- 241 + 85429 = 85670
Showing the first eight; more decompositions exist.
