Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740872, here are decompositions:
- 5 + 8740867 = 8740872
- 13 + 8740859 = 8740872
- 31 + 8740841 = 8740872
- 73 + 8740799 = 8740872
- 79 + 8740793 = 8740872
- 83 + 8740789 = 8740872
- 89 + 8740783 = 8740872
- 109 + 8740763 = 8740872
Showing the first eight; more decompositions exist.
