Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39906, here are decompositions:
- 5 + 39901 = 39906
- 19 + 39887 = 39906
- 23 + 39883 = 39906
- 29 + 39877 = 39906
- 37 + 39869 = 39906
- 43 + 39863 = 39906
- 59 + 39847 = 39906
- 67 + 39839 = 39906
Showing the first eight; more decompositions exist.
