Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71670, here are decompositions:
- 7 + 71663 = 71670
- 23 + 71647 = 71670
- 37 + 71633 = 71670
- 73 + 71597 = 71670
- 101 + 71569 = 71670
- 107 + 71563 = 71670
- 167 + 71503 = 71670
- 191 + 71479 = 71670
Showing the first eight; more decompositions exist.
