Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47178, here are decompositions:
- 17 + 47161 = 47178
- 29 + 47149 = 47178
- 31 + 47147 = 47178
- 41 + 47137 = 47178
- 59 + 47119 = 47178
- 67 + 47111 = 47178
- 127 + 47051 = 47178
- 137 + 47041 = 47178
Showing the first eight; more decompositions exist.
