Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16884, here are decompositions:
- 5 + 16879 = 16884
- 13 + 16871 = 16884
- 41 + 16843 = 16884
- 53 + 16831 = 16884
- 61 + 16823 = 16884
- 73 + 16811 = 16884
- 97 + 16787 = 16884
- 137 + 16747 = 16884
Showing the first eight; more decompositions exist.
