Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47970, here are decompositions:
- 7 + 47963 = 47970
- 19 + 47951 = 47970
- 23 + 47947 = 47970
- 31 + 47939 = 47970
- 37 + 47933 = 47970
- 53 + 47917 = 47970
- 59 + 47911 = 47970
- 67 + 47903 = 47970
Showing the first eight; more decompositions exist.
