Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47512, here are decompositions:
- 5 + 47507 = 47512
- 11 + 47501 = 47512
- 53 + 47459 = 47512
- 71 + 47441 = 47512
- 131 + 47381 = 47512
- 149 + 47363 = 47512
- 173 + 47339 = 47512
- 233 + 47279 = 47512
Showing the first eight; more decompositions exist.
