Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47090, here are decompositions:
- 3 + 47087 = 47090
- 31 + 47059 = 47090
- 73 + 47017 = 47090
- 97 + 46993 = 47090
- 157 + 46933 = 47090
- 223 + 46867 = 47090
- 229 + 46861 = 47090
- 271 + 46819 = 47090
Showing the first eight; more decompositions exist.
