Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66506, here are decompositions:
- 7 + 66499 = 66506
- 43 + 66463 = 66506
- 103 + 66403 = 66506
- 163 + 66343 = 66506
- 337 + 66169 = 66506
- 397 + 66109 = 66506
- 439 + 66067 = 66506
- 523 + 65983 = 66506
Showing the first eight; more decompositions exist.
