Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47072, here are decompositions:
- 13 + 47059 = 47072
- 31 + 47041 = 47072
- 79 + 46993 = 47072
- 139 + 46933 = 47072
- 211 + 46861 = 47072
- 241 + 46831 = 47072
- 349 + 46723 = 47072
- 409 + 46663 = 47072
Showing the first eight; more decompositions exist.
