Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47136, here are decompositions:
- 7 + 47129 = 47136
- 13 + 47123 = 47136
- 17 + 47119 = 47136
- 43 + 47093 = 47136
- 79 + 47057 = 47136
- 139 + 46997 = 47136
- 179 + 46957 = 47136
- 269 + 46867 = 47136
Showing the first eight; more decompositions exist.
