Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173778, here are decompositions:
- 5 + 173773 = 173778
- 37 + 173741 = 173778
- 71 + 173707 = 173778
- 79 + 173699 = 173778
- 107 + 173671 = 173778
- 109 + 173669 = 173778
- 127 + 173651 = 173778
- 131 + 173647 = 173778
Showing the first eight; more decompositions exist.
