Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47578, here are decompositions:
- 71 + 47507 = 47578
- 137 + 47441 = 47578
- 191 + 47387 = 47578
- 197 + 47381 = 47578
- 227 + 47351 = 47578
- 239 + 47339 = 47578
- 269 + 47309 = 47578
- 281 + 47297 = 47578
Showing the first eight; more decompositions exist.
