Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47420, here are decompositions:
- 3 + 47417 = 47420
- 13 + 47407 = 47420
- 31 + 47389 = 47420
- 67 + 47353 = 47420
- 103 + 47317 = 47420
- 127 + 47293 = 47420
- 151 + 47269 = 47420
- 199 + 47221 = 47420
Showing the first eight; more decompositions exist.
