Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51670, here are decompositions:
- 11 + 51659 = 51670
- 23 + 51647 = 51670
- 71 + 51599 = 51670
- 89 + 51581 = 51670
- 107 + 51563 = 51670
- 131 + 51539 = 51670
- 149 + 51521 = 51670
- 167 + 51503 = 51670
Showing the first eight; more decompositions exist.
