Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66444, here are decompositions:
- 13 + 66431 = 66444
- 31 + 66413 = 66444
- 41 + 66403 = 66444
- 61 + 66383 = 66444
- 67 + 66377 = 66444
- 71 + 66373 = 66444
- 83 + 66361 = 66444
- 97 + 66347 = 66444
Showing the first eight; more decompositions exist.
