Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75778, here are decompositions:
- 5 + 75773 = 75778
- 11 + 75767 = 75778
- 47 + 75731 = 75778
- 71 + 75707 = 75778
- 89 + 75689 = 75778
- 137 + 75641 = 75778
- 149 + 75629 = 75778
- 167 + 75611 = 75778
Showing the first eight; more decompositions exist.
