Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47428, here are decompositions:
- 11 + 47417 = 47428
- 41 + 47387 = 47428
- 47 + 47381 = 47428
- 89 + 47339 = 47428
- 131 + 47297 = 47428
- 149 + 47279 = 47428
- 191 + 47237 = 47428
- 239 + 47189 = 47428
Showing the first eight; more decompositions exist.
