Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10872, here are decompositions:
- 5 + 10867 = 10872
- 11 + 10861 = 10872
- 13 + 10859 = 10872
- 19 + 10853 = 10872
- 41 + 10831 = 10872
- 73 + 10799 = 10872
- 83 + 10789 = 10872
- 101 + 10771 = 10872
Showing the first eight; more decompositions exist.
