Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71432, here are decompositions:
- 3 + 71429 = 71432
- 13 + 71419 = 71432
- 19 + 71413 = 71432
- 43 + 71389 = 71432
- 73 + 71359 = 71432
- 79 + 71353 = 71432
- 103 + 71329 = 71432
- 139 + 71293 = 71432
Showing the first eight; more decompositions exist.
