Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47170, here are decompositions:
- 23 + 47147 = 47170
- 41 + 47129 = 47170
- 47 + 47123 = 47170
- 59 + 47111 = 47170
- 83 + 47087 = 47170
- 113 + 47057 = 47170
- 173 + 46997 = 47170
- 251 + 46919 = 47170
Showing the first eight; more decompositions exist.
