Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84872, here are decompositions:
- 3 + 84869 = 84872
- 13 + 84859 = 84872
- 61 + 84811 = 84872
- 79 + 84793 = 84872
- 181 + 84691 = 84872
- 199 + 84673 = 84872
- 223 + 84649 = 84872
- 241 + 84631 = 84872
Showing the first eight; more decompositions exist.
