Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47572, here are decompositions:
- 3 + 47569 = 47572
- 29 + 47543 = 47572
- 59 + 47513 = 47572
- 71 + 47501 = 47572
- 113 + 47459 = 47572
- 131 + 47441 = 47572
- 191 + 47381 = 47572
- 233 + 47339 = 47572
Showing the first eight; more decompositions exist.
