Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66626, here are decompositions:
- 73 + 66553 = 66626
- 97 + 66529 = 66626
- 103 + 66523 = 66626
- 127 + 66499 = 66626
- 163 + 66463 = 66626
- 223 + 66403 = 66626
- 283 + 66343 = 66626
- 457 + 66169 = 66626
Showing the first eight; more decompositions exist.
