Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43212, here are decompositions:
- 5 + 43207 = 43212
- 11 + 43201 = 43212
- 23 + 43189 = 43212
- 53 + 43159 = 43212
- 61 + 43151 = 43212
- 79 + 43133 = 43212
- 109 + 43103 = 43212
- 149 + 43063 = 43212
Showing the first eight; more decompositions exist.
