Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43512, here are decompositions:
- 13 + 43499 = 43512
- 31 + 43481 = 43512
- 61 + 43451 = 43512
- 71 + 43441 = 43512
- 101 + 43411 = 43512
- 109 + 43403 = 43512
- 113 + 43399 = 43512
- 181 + 43331 = 43512
Showing the first eight; more decompositions exist.
