Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38664, here are decompositions:
- 11 + 38653 = 38664
- 13 + 38651 = 38664
- 53 + 38611 = 38664
- 61 + 38603 = 38664
- 71 + 38593 = 38664
- 97 + 38567 = 38664
- 103 + 38561 = 38664
- 107 + 38557 = 38664
Showing the first eight; more decompositions exist.
