Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66562, here are decompositions:
- 29 + 66533 = 66562
- 53 + 66509 = 66562
- 71 + 66491 = 66562
- 113 + 66449 = 66562
- 131 + 66431 = 66562
- 149 + 66413 = 66562
- 179 + 66383 = 66562
- 269 + 66293 = 66562
Showing the first eight; more decompositions exist.
