Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47020, here are decompositions:
- 3 + 47017 = 47020
- 23 + 46997 = 47020
- 101 + 46919 = 47020
- 131 + 46889 = 47020
- 167 + 46853 = 47020
- 191 + 46829 = 47020
- 251 + 46769 = 47020
- 263 + 46757 = 47020
Showing the first eight; more decompositions exist.
