Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178174, here are decompositions:
- 5 + 178169 = 178174
- 23 + 178151 = 178174
- 47 + 178127 = 178174
- 71 + 178103 = 178174
- 83 + 178091 = 178174
- 107 + 178067 = 178174
- 137 + 178037 = 178174
- 173 + 178001 = 178174
Showing the first eight; more decompositions exist.
