Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47290, here are decompositions:
- 3 + 47287 = 47290
- 11 + 47279 = 47290
- 53 + 47237 = 47290
- 83 + 47207 = 47290
- 101 + 47189 = 47290
- 167 + 47123 = 47290
- 179 + 47111 = 47290
- 197 + 47093 = 47290
Showing the first eight; more decompositions exist.
