Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43072, here are decompositions:
- 5 + 43067 = 43072
- 23 + 43049 = 43072
- 53 + 43019 = 43072
- 59 + 43013 = 43072
- 83 + 42989 = 43072
- 149 + 42923 = 43072
- 173 + 42899 = 43072
- 233 + 42839 = 43072
Showing the first eight; more decompositions exist.
