Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1432, here are decompositions:
- 3 + 1429 = 1432
- 5 + 1427 = 1432
- 23 + 1409 = 1432
- 59 + 1373 = 1432
- 71 + 1361 = 1432
- 113 + 1319 = 1432
- 131 + 1301 = 1432
- 149 + 1283 = 1432
Showing the first eight; more decompositions exist.
