Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63906, here are decompositions:
- 5 + 63901 = 63906
- 43 + 63863 = 63906
- 53 + 63853 = 63906
- 67 + 63839 = 63906
- 83 + 63823 = 63906
- 97 + 63809 = 63906
- 103 + 63803 = 63906
- 107 + 63799 = 63906
Showing the first eight; more decompositions exist.
