Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4872, here are decompositions:
- 11 + 4861 = 4872
- 41 + 4831 = 4872
- 59 + 4813 = 4872
- 71 + 4801 = 4872
- 73 + 4799 = 4872
- 79 + 4793 = 4872
- 83 + 4789 = 4872
- 89 + 4783 = 4872
Showing the first eight; more decompositions exist.
