Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4878, here are decompositions:
- 7 + 4871 = 4878
- 17 + 4861 = 4878
- 47 + 4831 = 4878
- 61 + 4817 = 4878
- 79 + 4799 = 4878
- 89 + 4789 = 4878
- 127 + 4751 = 4878
- 149 + 4729 = 4878
Showing the first eight; more decompositions exist.
