Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47388, here are decompositions:
- 7 + 47381 = 47388
- 37 + 47351 = 47388
- 71 + 47317 = 47388
- 79 + 47309 = 47388
- 101 + 47287 = 47388
- 109 + 47279 = 47388
- 137 + 47251 = 47388
- 151 + 47237 = 47388
Showing the first eight; more decompositions exist.
