Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 898, here are decompositions:
- 11 + 887 = 898
- 17 + 881 = 898
- 41 + 857 = 898
- 59 + 839 = 898
- 71 + 827 = 898
- 89 + 809 = 898
- 101 + 797 = 898
- 137 + 761 = 898
Showing the first eight; more decompositions exist.
