Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47286, here are decompositions:
- 7 + 47279 = 47286
- 17 + 47269 = 47286
- 79 + 47207 = 47286
- 97 + 47189 = 47286
- 137 + 47149 = 47286
- 139 + 47147 = 47286
- 149 + 47137 = 47286
- 157 + 47129 = 47286
Showing the first eight; more decompositions exist.
