Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8872, here are decompositions:
- 5 + 8867 = 8872
- 11 + 8861 = 8872
- 23 + 8849 = 8872
- 41 + 8831 = 8872
- 53 + 8819 = 8872
- 89 + 8783 = 8872
- 131 + 8741 = 8872
- 173 + 8699 = 8872
Showing the first eight; more decompositions exist.
