Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71878, here are decompositions:
- 11 + 71867 = 71878
- 17 + 71861 = 71878
- 29 + 71849 = 71878
- 41 + 71837 = 71878
- 71 + 71807 = 71878
- 89 + 71789 = 71878
- 101 + 71777 = 71878
- 137 + 71741 = 71878
Showing the first eight; more decompositions exist.
