Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47398, here are decompositions:
- 11 + 47387 = 47398
- 17 + 47381 = 47398
- 47 + 47351 = 47398
- 59 + 47339 = 47398
- 89 + 47309 = 47398
- 101 + 47297 = 47398
- 191 + 47207 = 47398
- 251 + 47147 = 47398
Showing the first eight; more decompositions exist.
