Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66550, here are decompositions:
- 17 + 66533 = 66550
- 41 + 66509 = 66550
- 59 + 66491 = 66550
- 83 + 66467 = 66550
- 101 + 66449 = 66550
- 137 + 66413 = 66550
- 167 + 66383 = 66550
- 173 + 66377 = 66550
Showing the first eight; more decompositions exist.
