Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178748, here are decompositions:
- 67 + 178681 = 178748
- 109 + 178639 = 178748
- 127 + 178621 = 178748
- 139 + 178609 = 178748
- 151 + 178597 = 178748
- 181 + 178567 = 178748
- 211 + 178537 = 178748
- 307 + 178441 = 178748
Showing the first eight; more decompositions exist.
