Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71552, here are decompositions:
- 3 + 71549 = 71552
- 73 + 71479 = 71552
- 79 + 71473 = 71552
- 109 + 71443 = 71552
- 139 + 71413 = 71552
- 163 + 71389 = 71552
- 193 + 71359 = 71552
- 199 + 71353 = 71552
Showing the first eight; more decompositions exist.
