Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47964, here are decompositions:
- 13 + 47951 = 47964
- 17 + 47947 = 47964
- 31 + 47933 = 47964
- 47 + 47917 = 47964
- 53 + 47911 = 47964
- 61 + 47903 = 47964
- 83 + 47881 = 47964
- 107 + 47857 = 47964
Showing the first eight; more decompositions exist.
