Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 133566, here are decompositions:
- 7 + 133559 = 133566
- 23 + 133543 = 133566
- 47 + 133519 = 133566
- 67 + 133499 = 133566
- 73 + 133493 = 133566
- 127 + 133439 = 133566
- 149 + 133417 = 133566
- 163 + 133403 = 133566
Showing the first eight; more decompositions exist.
