Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66526, here are decompositions:
- 3 + 66523 = 66526
- 17 + 66509 = 66526
- 59 + 66467 = 66526
- 113 + 66413 = 66526
- 149 + 66377 = 66526
- 167 + 66359 = 66526
- 179 + 66347 = 66526
- 233 + 66293 = 66526
Showing the first eight; more decompositions exist.
